INTRODUCTION

Description of DevicesThe W7750 is the Constant Volume Air Handling Unit (CVAHU) Controller in the Excel 10 product line family. The CVAHU is a LONMARK® compliant device designed to control single zone and heat pump air handlers. W7750 systems control the space temperature in a given zone by regulating the heating and cooling equipment in the air handler that delivers air to that space. The W7750 air handler is typically an all-in-one constant air volume packaged unit, located on the roof of the building. In addition to standard heating and cooling control, the W7750 provides many options and advanced system features that allow state-of-the-art commercial building control. The W7750 Controller is capable of stand-alone operation; however, optimum functional benefits are achieved when the network communication capabilities are used. The W7750 utilizes the Echelon® LONWORKS® network (LONWORKS Bus) for communications, and conforms with the LONMARK HVAC Interoperability standard for Roof Top Unit Controllers (see Fig. 9).

The T7770 or T7560 direct-wired Wall Modules are used in conjunction with W7750 Controllers. The zone controlled by the W7750 Controller typically can use a T7770A through D or a T7560A,B Wall Module. Additional features available in T7770A through D models include analog setpoint input knob, override digital input pushbutton, override status LED and LONWORKS Bus network access jack. Additional features available in T7560A,B models include analog setpoint input knob, override digital input pushbutton, humidity sensor (T7650B model), override status LCD and digital display.

The Q7750A Excel 10 Zone Manager is a communications interface that allows devices on the LONWORKS Bus network to communicate with devices on the standard EXCEL 5000® System C-Bus. Fig. 1 shows an overview of a typical system layout. The Q7750A also provides some control and monitoring functions.

Fig. 1. Typical system overview.

Control ApplicationW7750 systems in commercial buildings typically incorporate a packaged air handler system that delivers a constant volume of air at preconditioned temperatures to the zone being served. Each zone is usually serviced by a separate AHU; however, sometimes two or more AHUs service the same zone. Note that the W7750 is not designed to control Variable Air Volume (VAV) air handlers or Multi-Zone air handlers, where one air handler simultaneously controls the space temperature in many zones.

The W7750 can control staged or modulating heating and cooling coils, mixed air economizer dampers, and the system fan. Control of heat pump units, where the compressor(s) is used for both cooling and heating, is also provided. The zone the W7750 services can use a T7770 or T7650 for space temperature sensing and an LONWORKS Bus network access for users. Fig. 2 shows a typical W7750 control application.

Fig. 2. Typical W7750 control application.

Control ProvidedThe W7750 Controller is designed to control a single air handler to maintain the units space temperature at the current setpoint. Heating and cooling control is provided for either staged or modulating equipment. Up to four stages of mechanical cooling and up to four stages of heating are allowed. Modulating outputs can be either floating type such as a Series 60 control, or Pulse Width Modulated (PWM W7750B,C only) control.

The economizer dampers can be controlled directly with floating or PWM outputs, or indirectly using a digital output as an enable/disable signal to a packaged economizer controller. The economizer enable function, which decides when to allow outdoor air to be used for free cooling, can be configured to one of ten strategies based on the inputs. For more details, see Appendix B�Sequences of Operation. When the economizer position is controlled from the W7750, the minimum position setting (for ventilation requirements) can be adjusted based on indoor air quality (IAQ) needs in the space. IAQ monitoring is provided through either a CO2 sensor or a digital input from a space-mounted IAQ limit switch.

For heat pump configurations, up to four compressors can be controlled, along with up to four stages of auxiliary heat, and a heat/cool change over valve. Including the supply fan, the combination of these items may not exceed eight outputs if a W7750B,C is used, or six outputs for a W7750A. (The eight outputs on the W7750C consist of five digital and three analog outputs.)

Like the W7751 VAV Box Controller, the W7750 Controller can monitor a space-mounted occupancy sensor, and a door/window contact. These inputs affect the operational mode of the controller (see Table 5 for a list of all possible modes of operation).

The W7750 Controller allows other controllers in the system to use the W7750s physical inputs and outputs. A digital input and an analog input can be configured to read switch states and voltage sensor values, respectively, and send them out over the LONWORKS Bus network. The Q7750A Zone Manager can use these values in custom control strategies. Additionally, two of the W7750 digital outputs are available for control program use. These outputs only respond to signals sent over the network, and are not controlled by the W7750 internal control algorithms.

Construction

ControllersThe Excel 10 W7750 Controller is available in three different models. The W7750A Model, which is a low cost controller made for simple single zone air handlers and heat pump controls. The W7750B,C Models are intended for more complex applications.

The W7750B,C Models use Triacs for their digital outputs, where as the W7750A Model uses dry-contact relays. The W7750C Model also has three analog outputs available on terminals 16, 17 and 18.

All wiring connections to the controller are made at screw terminal blocks. Connection for operator access to the LONWORKS Bus is provided by plugging the SLTA connector cable into the LONWORKS Bus communications jack.

The W7750A,B,C Models consist of a single circuit board that is mounted in a sheet metal subbase and protected by a factory snap-on cover. The three controllers have the same physical appearance except for terminals 16 through 20

(W7750A) and different labels next to the wiring terminals (see Fig. 3, 5 or 6). Wires are attached to the screw terminal blocks on both sides of the controller. The controllers mount with two screws (see Fig. 4 or 7). The W7750 can also be mounted using DIN rail. To mount the W7750 on DIN rail, purchase two DIN rail adapters (obtain locally) part number TKAD, from Thomas and Betts, see Fig. 8, then snap onto standard EN 50 022 35 mm by 7.5 mm (1-3/8 in. by 5/16 in.) DIN rail. DIN rail is available through local suppliers.

A channel in the cover allows the controller status LED to be visible when the cover is in place. There are no field-serviceable parts on the circuit board and, therefore, it is intended that the cover never be removed.

The W7750A,B,C can be mounted in any orientation. Ventilation openings were designed into the cover to allow proper heat dissipation regardless of the mounting orientation. See Fig. 4 and 7.

The input/output and control differences between the two models are summarized in Table 2. The I/O points in Table 2 are the free I/O points that are not reserved for Wall Module use.

Table 2. List of Differences in W7750A and W7750B,C Controllers.

a The T7770 or the T7560 Wall Modules includes I/O points for two analog inputs for the space temperature and the setpoint knob, a digital input for the Bypass pushbutton, and a digital output for the LED Bypass Indicator. These W7750 I/O points are configurable, but are normally used for the Wall Module.

Performance Specifications

Power:24 Vac with a minimum of 20 Vac and a maximum of 30 Vac at either 50 or 60 Hz. The W7750A power consumption is 6 VA maximum at 50 or 60 Hz. The W7750B,C power consumption is 12 VA maximum at 50 or 60 Hz.The W7750A,B,C is a NEC Class 2 rated device. This listing imposes limits on the amount of power the product can consume or directly control to a total of 100 VA.

Special Note for the W7750B,C Unit:The individual Triac outputs incorporate an internal common connection with the input power transformer. The Triacs provide a switched path from the hot side (R - high-side switching) of the transformer through the load to the common of the transformer. (Refer to Fig. 26 and 30 for low-side switching - J2 jumper.) The W7750B,C Controller design must use the same power transformer for any loads connected to that controller; see Fig. 30.

Each individual Triac is rated 1A at 30 Vac maximum. Under all operating conditions, the maximum load/source power budget for the W7750B,C Controller is 100 VA. Actual allowable Triac current is 500 mA MAX.

Communications:The W7750A,B,C Controller uses a Free Topology Transceiver (FTT) transformer-coupled communications port running at 78 kilobits per second (kbps). Using the transformer-coupled communications interface offers a much higher degree of common-mode noise rejection while ensuring dc isolation.

Approved cable types for LONWORKS Bus communications wiring is Level IV 22 AWG (0.34 mm2) plenum or nonplenum rated unshielded, twisted pair, solid conductor wire. For

nonplenum areas, use Level IV 22 AWG (0.34 mm2) such as: U.S. part AK3781 (one pair), U.S. part AK3798 (one pair stranded), or U.S. part AK3782 (two pair). In plenum areas, use plenum-rated Level IV, 22 AWG (0.34 mm2) such as U.S. part AK3791 (one pair) or U.S. part AK3792 (two pair). (See Tables 9 and 11 for part numbers.) Contact Echelon Corp.

Fig. 8. DIN rail adapters.

The FTT supports polarity insensitive free topology wiring. This frees the system installer from wiring using a specific bus topology. T-tap, star, loop, and mixed wiring topologies are all supported by this architecture. The maximum LONWORKS Bus length when using a combination of T-tap, star, loop, and bus wiring (singly terminated) is 1640 ft. (500m) with the maximum node-to-node length of 1312 ft. (400m). In the event that the total wire length is exceeded, then a Q7740A 2-Way Repeater or a Q7740B 4-Way Repeater can be used to allow the number of devices to be spread out as well as increasing the length of wire over which they communicate. The maximum number of repeaters per segment is one. A Q7751A,B LONWORKS Bus Router can also be used to effectively double the maximum LONWORKS Bus length.

NOTE: For LCBS the router must be configured as a repeater.

The advantage of using the router is that it segregates traffic to a segment while when using the repeater, all traffic is repeated on each segment. When utilizing a doubly

terminated LONWORKS Bus structure, use a continuous daisy-chain with no stubs or taps from the main backbone, The maximum LONWORKS Bus length is 4593 ft. (1400m) with the maximum node-to-node length of 3773 ft. (1150m).

FTT networks are very flexible and convenient to install and maintain, but it is imperative to carefully plan the network layout and create and maintain accurate documentation. This aids in compliance verification and future expansion of the FTT network. This also keeps unknown or inaccurate wire run lengths, node-to-node (device-to-device) distances, node counts, total wire length, inaccurate repeater/router locations, and misplaced or missing terminations minimized. Refer to LONWORKS Bus Wiring Guidelines form, 74-2865 for complete description of network topology rules.

IMPORTANTWhen any device is energized by a Triac, the device must be able to sink a minimum of 25 mA.

NOTE: Triacs sink current to the 24 Vac hot (high side switching - factory default) or common (low side switching); see Fig. 30 for wiring example of high side switching.

IMPORTANTIf non-Honeywell motors, actuators, or transducers are to be used with Excel 10 Controllers, Triac compatibility must be verified (see previous NOTE).

74-2958�2 24

Staged Heating/Cooling ControlStaged equipment control is available for up to four stages of heating or four stages of cooling. On the W7750, the stages are activated through digital outputs (Triacs on the W7750B,C and dry-contact relays on the W7750A) one for each stage wired to 24 Vac contactors (see Fig. 27 and 30 in Step 4. Prepare Wiring Diagrams section for wiring details). Note that the number of physical Digital Outputs (DOs) on the controller limits the total number of stages that can be controlled. For example, the W7750A Model has six digital outputs, and because one is used for the supply fan, there are five DOs available for any combination of heating and cooling stages (with a maximum of four stages of heating and four stages for cooling). The W7750B Model offers two additional DOs, for a total of eight. The W7750C offers five DOs and three Analog Outputs (AOs). Fig. 13 shows a typical application of two stages of heat and two stages of cooling.

Fig. 13. Fan with two stages of heating and two stages of cooling.

Modulating Heating/Cooling ControlThe W7750 Controller provides modulating equipment control for heating and cooling equipment (and economizer dampers, see Fig. 16) using either Series 60 Floating Control or Pulse Width Modulated (PWM) control, (PWM control is available on the W7750B,C only). The Series 60 Modulating Control is provided through two Relay digital outputs on the W7750A (for economizer only) or two Triac digital outputs on the W7750B,C (one to pulse the valve actuator open and one to pulse it closed). PWM control positions the actuator based on the length, in seconds, of the pulse from the digital output. For PWM, the controller outputs a pulse whose length consists of two parts, a minimum and a maximum. The minimum pulse

time represents the analog value of 0 percent and the maximum pulse length that represents an analog value of 100 percent. If the analog value is greater than 0 percent, an additional time is added to the minimum pulse time. The length of time added is directly proportional to the magnitude of the analog value. The PWM actuator will begin to use the analog value at the end of the pulse and will continue to use this value until a new pulse is received. Refer to Appendix B under PWM Control for an example. Series 60 actuators are generally less expensive than those for PWM, but the trade-off is that PWM requires only a single controller digital output while floating control uses two DOs. Refer to Appendix B under Series 60 Modulating Control for an example. Fig. 14 illustrates a system with modulating heating and cooling (see Fig. 29 and 31 in Step 4. Prepare Wiring Diagrams section.

Fig. 14. Fan, modulating heating and modulating cooling.

NOTE: Pneumatically actuated valves can be controlled using a pneumatic transducer device. See Fig. 17. Also, transducer devices are available from third party vendors to convert PWM outputs to a voltage or current signal if desired.

Heat Pump ControlThe W7750 Controller handles heat pump applications similarly to staged heating/cooling control. Heat pump applications are supported by providing outputs for up to four compressor stages, a change-over relay for the refrigerant reversing valve, and up to four stages of auxiliary heat. Note that the W7750A Model has six digital outputs, and therefore, with one DO used for the supply fan and one for the change-over relay, there are four outputs available for any combination of compressors and auxiliary heat stages. The W7750B Model offers two additional DOs for a total of eight, while the W7750C Model offers five DOs and 3 AOs. Fig. 15 illustrates a typical heat pump system with auxiliary heat.

Economizer ControlEconomizer control is available concurrently with any configuration in the W7750 when DOs are not all used by the heating and cooling equipment. Two types of economizer controls are supported by the W7750 Controller, modulating control and enable/disable control. Modulating control can be either Series 60 Floating Control or PWM control (PWM

control is available on the W7750B,C only). A discharge air temperature sensor is required for modulating economizer damper control. Enable/disable control is provided to emulate the Honeywell T7300 thermostat economizer operation, where a DO tracks the occupancy status of the controller. An external packaged economizer control then modulates the dampers. For modulating control, the economizer is enabled or disabled based on one of ten available strategies (see Appendix B�Sequences of Operation�Economizer Enable/Disable Control section, for further details). Fig. 16 illustrates a system with modulating economizer dampers (see Fig. 29, 31, 32 and 35 in Step 4. Prepare Wiring Diagrams section, for wiring details).

Pneumatic Actuator ControlThe W7750B,C Controller can control pneumatic actuators for any or all of the three modulating outputs provided by the control algorithm (heat, cool and economizer). Control of pneumatic water/steam valves and damper actuators is provided through a transducer device using either Series 60 Floating Control or PWM DOs. A floating-to-pneumatic, or a PWM-to-pneumatic transducer is required for each output signal. The W7750A Controller can drive Series 60 Floating Control for only economizer control. There are no PWM outputs configurable on the W7750A model.

For projects with existing pneumatically actuated reheat valves, the Excel 10 W7750 Controller output must be converted to a pneumatic signal using a transducer device developed for use with Excel 10 Controllers. The transducer is available through Honeywell, or directly from a third party manufacturer.

Fig. 17 depicts a typical W7750 System with modulating heating valve using a pneumatic valve actuator. Also see Fig. 37 for wiring an RP7517B Pneumatic Transducer to a W7750C Controller.

NOTE: When choosing the pneumatic pressure range, make sure that the close-off pressure is 2 to 3 psi greater than that of the spring range. When using a spring range of 5 to 10 psi with 10 psi as the closed posi-tion, do not use a 0 to 10 psi model transducer; use a 0 to 20 psi transducer as the recommended selec-tion.

Fig. 17. Modulating heat with pneumatic valve actuator.

Mixed Output-type ControlThe W7750B,C Controller provides control for mixed-output-types of applications such as PWM heating and staged cooling control occurring simultaneously with Series 60 Floating Economizer Damper Control.

Occupancy SensorExcel 10 W7750 Controllers provide a digital input for connection to an occupancy sensor. This is a device, such as a passive infrared motion detector, that contains a dry contact

(see following NOTE) closure to indicate whether or not people are present in the space. The Excel 10 W7750 Controller expects a contact closure to indicate the space is Occupied. See Fig. 27 through 35 in Application Step 4, Prepare Wiring Diagrams, for details on wiring connections.

The control algorithm in the Excel 10 Controller uses the occupancy sensor, if configured, to determine the Effective Occupancy (see Table 5) mode of operation. If the Time Of Day (TOD) schedule indicates an Occupied state, and the occupancy sensor contact is closed, the Effective Occupancy mode is Occupied. However, if the TOD schedule indicates an Occupied state and the occupancy sensor contact is open, then the Effective Occupancy mode is STANDBY. The temperature control algorithm is then controlled to the STANDBY Cooling and Heating Setpoints.

If the occupancy sensor is not configured, a local controller can be put in the STANDBY mode only by either a one-to-one association of the occupancy sensor from another Excel 10 Controller to the local controller, or by receiving the STANDBY mode signal via the LONWORKS Bus.

NOTE: The Excel 10 Controller has limited power available (only 9 mA at 4.8 volts) for checking the digital inputs for contact closures. It is very important that the device used contains high quality, noncorroding con-tacts with resistivity that does not degrade; that is, increase over time. Use noble metal (such as gold or silver), or pimpled or sealed contacts to assure con-sistent, long-term operation.

Window Open/Closed Digital InputA digital input is also provided for detecting whether a window in the space was opened. The Excel 10 W7750 Controller can be connected to a dry contact (see the following NOTE and Fig. 27 through 35 in Application Step 4. Prepare Wiring Diagrams, for details) or a set of contacts wired in series (for monitoring multiple windows) to verify that the window(s) are closed. The algorithm expects a contact closure to indicate the window is closed. If an open window is detected, the algorithm changes the mode of operation to FREEZE_PROTECT, which shuts down the control functions, and watches for low space temperature conditions. The frost protection setpoint is 46.4°F (8°C), and the frost alarm occurs at 42.8°F (6°C).

NOTE: (This is the same NOTE as in the Occupancy Sensor section.) The Excel 10 has limited power available (only 9 mA at 4.8 volts) for checking the digital inputs for contact closures. It is very important that the device used contains high quality, noncorroding con-tacts with resistivity that does not degrade; that is, increase over time. Use noble metal (such as gold or silver), or pimpled or sealed contacts to assure con-sistent, long-term operation.

Wall Module OptionsAs previously discussed, there are four basic varieties of the T7770 Wall Modules and two of the T7560 Digital Wall Module (see the Product Names and the Construction sections). Also, a T7770 and T7560 Wall Modules can be shared among two or more W7750s. The control algorithm must be given this wall module information when configuring the W7750.

Dirty Filter MonitorThe air filter in the air handler can be monitored by the W7750 and an alarm is issued when the filter media needs replacement. The two methods of monitoring the filter are:

1. Connecting a differential pressure switch to a digital input on the W7750A or W7750B,C.

2. Wiring a 2 to 10V differential pressure sensor (such as the P7640A,B 4-20 mA with 500 ohm resistor) to a voltage input on the W7750B,C. If the analog input sensor is used, its measured value 0 to 5 in. w.c. (0 to 1.25 kPa) is compared to a user-selectable setpoint [FltrPressStPt�valid range: 0 to 5 in. w.c. (0 to 1.25 kPa)], and the Dirty Filter alarm is issued when the pressure drop across the filter exceeds the setpoint.

Indoor Air Quality (IAQ) OverrideThe Excel 10 W7750 Controller provides IAQ ventilation control using one of two different methods of detecting poor air quality. The first is with an IAQ switch device connected to a digital input on the W7750 Controller, where a contact closure indicates poor air quality, and initiates the IAQ Override mode. The device can detect poor air quality using any desired measure such as CO2, VOC, CO, etc. The second method, which is only available on the W7750B,C, is through an analog input that connects to a CO2 sensor (0 to 10 Vdc, as provided with the C7232A,B). The measured value of CO2 from this sensor (0 to 2000 PPM) is compared to the setpoint (IAQSetpt). When the CO2 level is higher than the

setpoint (800 PPM adjustable), the IAQ Override is initiated. The IAQSetpt hysteresis is 50 PPM, IAQ Override is deactivated at a CO2 level less than 50 PPM below setpoint.

The effect of initiating the IAQ Override mode is that the economizer dampers are allowed to open above the standard minimum position setting to allow more fresh air to enter the building. See Appendix B�Sequences of Operation, for further control details.

Smoke ControlThe Excel 10 W7750 Controller supports smoke-related control strategies that are initiated either via a network command (DestEmergCmd) or from a local (physically connected) smoke detector digital input. The details of the W7750 smoke-related control operation are described in Appendix B�Sequences of Operation.

Freeze Stat (W7750B2011 or W7750C)A freeze stat can be monitored by the W7750 and issue a freeze stat alarm indicating the CVAHU is in danger of freezing its coil. The details of the W7750 freeze stat related control operation are described in Appendix B�Sequences of Operation.

Modes of OperationThe possible modes of operation for the W7750 Controller are listed in Table 5.

Table 5. Modes Of Operation For The Excel 10 W7750 Controller .Mode Description Events causing a controller to switch to this mode

Effective Occupancy (User Address: StatusOcc)OCCUPIED Controller is in Occupied mode Any of the following: Network input (DestSchedOcc) containing a

time-of-day schedule or a Time Clock DI, Occupancy Sensor DI; or from Network input (DestManMode) for manual override to OCC mode. DestManMode has the highest priority, followed by the Time Clock DI, and then DestSchedOcc.

STANDBY Controller is in Standby mode Either: (A) Network input (DestSchedOcc) containing a time-of-day schedule or other LONWORKS Bus node is STANDBY, or (B) Network input (DestSchedOcc) is OCCUPIED and the Occupancy Sensor DI is UNOCCUPIED.

UNOCCUPIED Controller is in Unoccupied mode Network input (DestSchedOcc) containing a time-of-day schedule or the network input DestManOcc has a value of UNOCCUPIED.

BYPASS OCCUPIED

Controller is in Occupied mode through a Bypass command

This mode is derived from the schedule occupancy (DestSchedOcc) having a state of UNOCCUPIED and a manual request for occupancy from one of three sources. Two of these are signals originated external to the unit, and received by DestManOcc and DestBypass. The third source for an occupancy request is from an override button located on a wall module. These three sources are arbitrated in a scheme determined by the configuration parameter (Network Wins or Last-in Wins from OvrdPriority).

Override Modes (User Address: StatusOvrd)OCCUPIED Controller occupancy mode was

overridden to Occupied modeNetwork input (DestManOcc) containing a time-of-day schedule override signal of OCCUPIED from another LONWORKS Bus device.

STANDBY Controller occupancy mode was overridden to Standby mode

Network input (DestManOcc) containing a time-of-day schedule override signal of STANDBY from another LONWORKS Bus device.

UNOCCUPIED Controller occupancy mode was overridden to Unoccupied mode

Network input (DestManOcc) containing a time-of-day schedule override signal of UNOCCUPIED from another LONWORKS Bus device.


74-2958�2 28

NOTE: During all modes all digital and analog physical inputs are periodically read, the diagnostic output network variables can be polled, the input network variables are received, and the output network variables are sent periodically.

APPLICATION STEPS

OverviewThe seven application steps shown in Table 6 are planning considerations for engineering an Excel 10 W7750 System. These steps are guidelines intended to aid understanding of the product I/O options, bus arrangement choices, configuration options and the Excel 10 W7750 Controller role in the overall LCBS/EXCEL 5000® OPEN� SYSTEM architecture.

Table 6. Application Steps.

29 74-2958�2

Step 1. Plan the SystemPlan the use of the W7750 Controllers according to the job requirements. Determine the location, functionality and sensor or actuator usage. Verify the sales estimate of the number of W7750 Controllers, T7770 and T7560 Wall Modules required for each model type. Also check the number and type of output actuators and other required accessories.

When planning the system layout, consider potential expansion possibilities to allow for future growth. Planning is very important to be prepared for adding HVAC systems and controllers in future projects.

T7560 Wall Modules can only be hard-wired, they have no LONWORKS Bus access. T7770 Wall Modules can be installed as either hard-wired I/O-only devices or additional wiring can be run to them (for the LONWORKS Bus network) to allow a LONSPEC� or Care user access to the LONWORKS Bus. The application engineer needs to determine how many wall modules, T7770s and T7560s are required. All T7770 Wall Modules, except the T7770A1006, can be connected via the LONWORKS Bus jack. Also the application engineer needs to know how many T7770s without LONWORKS Bus network connections are being installed on the job, and then clearly document which wall modules (if any) have network access. This information is required during installation to ensure that the proper number and type of wires are pulled to the wall modules, and the building operators are informed about where they can plug in to the LONWORKS Bus network with a portable operator terminal (see Fig. 18, 19 and 20). Refer to Step 4. Prepare Wiring Diagrams for details, about the about the wiring differences between the two types.

The FTT communication wiring, (LONWORKS Bus) between controllers is a free topology scheme that supports T-tap, star, loop, and mixed wiring architecture. Refer to the LONWORKS Bus Wiring Guidelines form, 74-2865 for complete description of network topology rules. See Application Step 3. Lay Out Communications and Power Wiring, for more information on bus wiring layout, and see Fig. 27 through 35 in Application Step 4. Prepare Wiring Diagrams, for wiring details.

Fig. 18. Connecting the portable operator terminal to the LONWORKS® Bus.

The application engineer must review the Direct Digital Control (DDC) job requirements. This includes the Sequences of Operation for the W7750 units, and for the system as a whole. Usually there are variables that must be passed between the W7750 Controllers and other zone controller(s), or central plant controller(s) that are required for optimum system-wide operation. Typical examples are the TOD Occ/Unocc signal, the outdoor air temperature, the demand limit control signal, and the smoke control mode signal.

It is important to understand these interrelationships early in the job engineering process to ensure implementation when configuring the controllers. (See Application Step 6. Configure Controllers, for information on the various Excel 10 parameters and on Excel 10 point mapping.)

Step 2. Determine Other Bus Devices RequiredA maximum of 62 nodes can communicate on a single LONWORKS Bus segment. Each W7750 (CVAHU) Controller constitutes one node. If more nodes are required, a Q7740A1008 Two-way Repeater, a Q7740B1006 Four-way Repeater, or a Q7751A,B Router is necessary. Using a router allows up to 125 nodes, divided between two LONWORKS Bus segments. The router accounts for two of these nodes (one node on each side of the router); an XL5000 Q7750A Excel 10 Zone Manager takes one node and two nodes are available for operator terminal nodes, leaving 120 nodes available for Excel 10/15 Controllers. All 120 controllers are able to talk to each other through the repeater/router.

Each LONWORKS Bus segment is set up with two unused nodes to allow for a LONSPEC�/LONSTATION� or CARE operator terminal to be connected to the LONWORKS Bus. Multiple CARE terminals (for XL5000 system), or one LonSpec and one LonStation (for LCBS systems) can be connected to the LONWORKS Bus at the same time. Table 7 summarizes the LONWORKS Bus segment configuration rules.

Table 7. LONWORKS® Bus Configuration Rules and Device Node Numbers.

Refer to the LONWORKS Bus Wiring Guidelines form, 74-2865 for complete description of network topology rules and the maximum wire length limitations. If longer runs are required, a Q7740A 2-Way or Q7740B 4-Way Repeater can be added to extend the length of the LONWORKS Bus. A Q7751A,B Router can be added to partition the system into two segments and effectively double the length of the LONWORKS Bus. Only one router is allowed with each Excel 10 Zone Manager, and each network segment can have a maximum of one repeater.

NOTE: LCBS does not support a router unless it is config-ured as a repeater.

In addition, all LONWORKS Bus segments require the installation of a 209541B Termination Module for a singly terminated LONWORKS Bus or two 209541B Termination Modules for a doubly terminated LONWORKS Bus. For more details on LONWORKS Bus termination, refer to the LONWORKS Bus Wiring Guidelines form, 74-2865, or see Application Step 3. Lay Out Communications and Power Wiring, and the LONWORKS Bus Termination Module subsection in Application Step 4.

Step 3. Lay Out Communications and Power Wiring

LONWORKS® Bus LayoutThe communications bus, LONWORKS Bus, is a 78-kilobits per second (kbps) serial link that uses transformer isolation and differential Manchester encoding. Approved cable types for

LONWORKS Bus communications wiring is Level IV 22 AWG (0.34 mm2) plenum or non-plenum rated unshielded, twisted pair, solid conductor wire. For nonplenum areas, use Level IV 22 AWG (0.325 mm2), such as U.S. part AK3781 (one pair) or U.S. part AK3782 (two pair). In plenum areas, use plenum-rated Level IV, 22 AWG (0.325 mm2) such as U.S. part AK3791 (one pair) or U.S. part AK3792 (two pair). See Tables 9 and 11 for part numbers. Contact Echelon Corp. Technical Support for the recommended vendors of Echelon approved cables. The FTT communications bus, LONWORKS Bus, supports a polarity insensitive, free topology wiring scheme that supports T-tap, star, loop, and mixed bus wiring.

LONWORKS Bus networks can be configured in a variety of ways, so refer to the LONWORKS Bus Wiring Guidelines form, 74-2865 for complete description of network topology rules and Table 7. Fig. 19 and 20 depict two typical LONWORKS Bus network topologies; One has only one doubly terminated LONWORKS Bus segment that has 60 nodes or less, and one showing two singly terminated LONWORKS Bus segments that has 120 nodes or less (60 MAX per each segment). The bus configuration is set up using the Network Manager tool from within LONSPEC� or CARE.

NOTE: For wiring details see the LONWORKS Bus Termination Module subsection in Step 4. For wall module wiring, U.S. part AK3782 (non-plenum) or U.S. part AK3792 (plenum) can be used. For a LONWORKS Bus that is a doubly terminated daisy-chain, these cables contain two twisted pairs (one for the run down to the wall module, and one for the run back up to the controller) for ease of installation.

IMPORTANTNotes on communications wiring:� All field wiring must conform to local codes and

ordinances or as specified on installation wiring diagrams.

� Approved cable types for LONWORKS Bus communi-cations wiring is Level IV 22 AWG (0.34 mm2) plenum or non-plenum rated unshielded, twisted pair, solid conductor wire. For nonplenum areas, use Level IV 22 AWG (0.34 mm2), such as U.S. part AK3781 (one pair) or U.S. part AK3782 (two pair). In plenum areas, use plenum-rated Level IV, 22 AWG (0.34 mm2) such as U.S. part AK3791 (one pair) or U.S. part AK3792 (two pair). See Tables 9 and 11 for part numbers. Contact Echelon Corp. Technical Support for the recommended vendors of Echelon approved cables.

� Unswitched 24 Vac power wiring can be run in the same conduit as the LONWORKS Bus cable.

� Do not use different wire types or gauges on the same LONWORKS Bus segment. The step change in line impedance characteristics causes unpredictable reflections on the bus. When using different types is unavoidable, use a Q7751A,B Router at the junction.

� In noisy (high EMI) environments, avoid wire runs parallel to noisy power cables, or lines containing lighting dimmer switches, and keep at least 3 in. (76 mm) of separation between noisy lines and the LONWORKS Bus cable.

� Make sure that neither of the LONWORKS Bus wires is grounded.

Fig. 20. Wiring layout for two singly terminated LONWORKS® Bus segments.

Power WiringA power budget must be calculated for each Excel 10 W7750 Controller to determine the required transformer size for proper operation. A power budget is simply the summing of the maximum power draw ratings (in VA) of all the devices to be controlled by an Excel 10 W7750 Controller. This includes the controller itself, the equipment actuators (ML6161, or other motors) and various contactors and transducers, as appropriate, for the Excel 10 configuration.

Power Budget Calculation ExampleThe following is an example power budget calculation for a typical Excel 10 W7750B Controller.

Assume a W7750 unit with a fan, two stages of D/X cooling, modulating steam valve for heating, and modulating economizer dampers. The power requirements are:

NOTE: For this example, assume the cooling stage outputs are wired into a compressor control circuit and, therefore, have no impact on the power budget.)

M6410A Steam 0.7 TRADELINE®

Heating Coil Valve Catalog, 0.32A at 24 Vac

TOTAL: 35.9 VA

The Excel 10 System example requires 35.9 VA of peak power; therefore, a 40 VA AT72D Transformer is able to provide ample power for this controller and its accessories. Alternatively, a 75 VA AT88A Transformer could be used to power two Excel 10 Systems of this type, or a 100 VA AT92A Transformer could be used to power two of these Excel 10 Systems and meet NEC Class 2 restrictions (no greater than 100 VA). See Fig. 22 and 23 for illustrations of power wiring details. See Table 8 for VA ratings of various devices.

Table 8. VA Ratings For Transformer Sizing.

For contactors and similar devices, the in-rush power ratings should be used as the worst case values when performing power budget calculations. Also, the application engineer must consider the possible combinations of simultaneously energized outputs and calculate the VA ratings accordingly. The worst case, that uses the largest possible VA load, should be determined when sizing the transformer.

Line LossExcel 10 Controllers must receive a minimum supply voltage of 20 Vac. If long power or output wire runs are required, a voltage drop due to Ohms Law (I x R) line loss must be considered. This line loss can result in a significant increase in total power required and thereby affect transformer sizing. The following example is an I x R line-loss calculation for a 200 ft. (61m) run from the transformer to a W7750 Controller drawing 37 VA using two 18 AWG (1.0 mm2) wires.

The formula is:Loss = [length of round-trip wire run (ft.)] X [resistance in

wire (ohms per ft.)] X [current in wire (amperes)]From specification data:

18 AWG twisted pair wire has 6.52 ohms per 1000 feet.Loss = [(400 ft.) X (6.52/1000 ohms per ft.)] X

[(37 VA)/(24V)] = 4.02 voltsThis means that four volts are going to be lost between the transformer and the controller; therefore, to assure the controller receives at least 20 volts, the transformer must output more than 24 volts. Because all transformer output voltage levels depend on the size of the connected load, a larger transformer outputs a higher voltage than a smaller one for a given load. Fig. 21 shows this voltage load dependence.

In the preceding I x R loss example, even though the controller load is only 37 VA, a standard 40 VA transformer is not sufficient due to the line loss. From Fig. 21, a 40 VA transformer is just under 100 percent loaded (for the 37 VA controller) and, therefore, has a secondary voltage of 22.9 volts. (Use the lower edge of the shaded zone in Fig. 21 that represents the worst case conditions.) When the I x R loss of four volts is subtracted, only 18.9 volts reaches the controller, which is not enough voltage for proper operation.

In this situation, the engineer basically has three alternatives:1. Use a larger transformer; for example, if an 80 VA

model is used, see Fig. 21, an output of 24.4 volts minus the four volt line loss supplies 20.4V to the controller. Although acceptable, the four-volt line-loss in this example is higher than recommended. See the following IMPORTANT.

2. Use heavier gauge wire for the power run. 14 AWG (2.0 mm2) wire has a resistance of 2.57 ohms per 1000 ft. which, using the preceding formula, gives a line-loss of only 1.58 volts (compared with 4.02 volts). This would allow a 40 VA transformer to be used. 14 AWG (2.0 mm2) wire is the recommended wire size for 24 Vac wiring.

3. Locate the transformer closer to the controller, thereby reducing the length of the wire run, and the line loss. The issue of line-loss is also important in the case of the output wiring connected to the Triac digital outputs. The same formula and method are used. The rule to remember is to keep all power and output wire runs as short as practical. When necessary, use heavier gauge wire, a bigger transformer, or install the transformer closer to the controller.

IMPORTANTNo installation should be designed where the line loss is greater than two volts to allow for nominal operation if the primary voltage drops to 102 Vac (120 Vac minus 15 percent).

To meet the National Electrical Manufacturers Association (NEMA) standards, a transformer must stay within the NEMA limits. The chart in Fig. 21 shows the required limits at various loads.

With 100 percent load, the transformer secondary must supply between 23 and 25 volts to meet the NEMA standard. When a purchased transformer meets the NEMA standard DC20-1986, the transformer voltage-regulating ability can be considered reliable. Compliance with the NEMA standard is voluntary.

The following Honeywell transformers meet this NEMA standard:

IMPORTANTIf the W7750 Controller is used on Heating and Cooling Equipment (UL 1995 U.S. only) devices and the transformer primary power is more than 150 volts, connect the transformer secondary to earth ground, see Fig. 24.

Fig. 24. Transformer power wiring details for one Excel 10 used in UL 1995 equipment (U.S. only).

IMPORTANTNotes on power wiring:

� All field wiring must conform to local codes and ordi-nances or as specified on installation wiring dia-grams.

� To maintain NEC Class 2 and UL ratings, the installa-tion must use transformers of 100 VA or less capac-ity.

� For multiple controllers operating from a single trans-former, the same side of the transformer secondary must be connected to the same input terminal in each controller (21 on the W7750A and 24 on the W7750B,C) and the ground terminals must be con-nected to a verified earth ground for each controller in the group. See Fig. 23. (Controller configurations are not necessarily limited to three devices per trans-former.)

� For the W7750B,C Controller (which has Triac out-puts), all output devices must be powered from the same transformer as the one powering the Excel 10 W7750 Controller.

� Use the heaviest gauge wire available, up to 14 AWG (2.0 mm2) with a minimum of 18 AWG (1.0 mm2) for all power and earth ground connections.

� To minimize EMI noise, do not run Triac output wires in the same conduit as the input wires or the LON-WORKS Bus communications wiring.

� Unswitched 24 Vac power wiring can be run in the same conduit as the LONWORKS Bus cable.

� Make earth ground connections with the shortest possible wire run using 14 AWG (2.0 mm2) wire. A good earth ground is essential for W7750 operation. Ideally, connect the earth ground to the ground bus at a motor control center or circuit breaker panel. However, if the nearest ideal earth ground is inac-cessible, consider an alternate source for earth ground. Metal water pipe is generally a good ground, but do not use sprinkler pipe if prohibited by local codes. Attention must be given when duct work, con-duit, or rebar are to be considered as ground sources. It is the responsibility of the installer to assure that these structures are tied back to a known earth ground.

Step 4. Prepare Wiring Diagrams

General ConsiderationsThe purpose of this step is to assist the application engineer in developing job drawings to meet job specifications. Wiring details are included for the W7750A,B,C Controllers and the T7770 and T7560A,B Wall Modules. The drawings detail I/O, power, and LONWORKS Bus communication wiring connections.

NOTE: For field wiring, when two or more wires, other than 14 AWG (2.0 mm2) are to be attached to the same connector block terminal, be sure to twist them together. Deviation from this rule can result in improper electrical contact. See Fig. 25.

The connector block terminals on the W7750 Controllers and on the T7770 Wall Modules accept 14 through 22 AWG (2.0 to 0.34 mm2) wire. The connector block terminals on the T7560A,B Wall Modules accept 18 through 22 AWG (1.0 to 0.34 mm2) wire. Table 9 lists wiring types, sizes, and length restrictions for Excel 10 products.

Table 9. Field Wiring Reference Table (Honeywell listed as AK#### or equivalent).

W7750 ControllersFig. 27 through 35 illustrate W7750A,B,C Controller wiring for various configurations. Connections to the wall module terminals (2 through 6) and the communications terminals (14

and 15) are made at terminal blocks. Connection for access to the LONWORKS Bus is provided by plugging the connector into the communications jack.

IMPORTANTIf the W7750A controller is configured by LONSPEC� or Care, the outputs may be assigned in different order than the factory defaults. Use the Custom Wiring function to re-assign the outputs to the desired terminals.

The W7750B,C Versions are preconfigured with the same factory default setup as the W7750A Model; however, some terminals for wiring connections differ on the W7750B,C Models. See Fig. 30 for the terminal names on the W7750B Model and Fig. 35 for the terminal names on the W7750C Model. The factory default configuration of the digital output points on the W7750B,C Models follow (terminal names are from the W7750A):

Factory Default Digital Outputs

The Wall Module terminals are identical for the W7750A,B,C Models.

The W7750B,C Models offers two voltage/current sensor input terminals. When current-type sensors (4 to 20 mA) are configured, the W7750B,C automatically switches a 249 ohm resistor into the sensing circuit; so no external resistor is required. The W7750A Model does not support voltage or current inputs.

NOTE: If using factory defaults, Di1 is local Time clock input, and the DI-2 input is configured for ScheduleMaster (nvoIO.SchedMaster). For a stand-alone unit, either connect an external time clock to terminals 9 and 10 or put a jumper on terminals 9 and 10 (using a jumper puts the controller in continuous occupied mode).

See Fig. 36 or 37 to wire a pneumatic transducer to a W7750B or W7750C.

Fig. 36. Series 60 pneumatic transducer to W7750B,C.

To use the analog outputs on the W7750C with 2 to 10V actuators or transducers, a 500 ohm (1 percent or better tolerance) resistor must be placed across the 4 to 20 mA devices input and ground terminal. See Fig. 37 for an example. The resistor converts a 4 to 20 mA signal into a 2 to 10V signal.

NOTE: Wire the 500 ohm resistor physically as close as possible to the driven device. If the resistor is located far away from the driven device, it is possible that noise will be added onto the 2 to 10V signal to ground line. This noise could cause an actuator to re-position (jitter) and reduce the actuators life.

Fig. 37. RP7517B Pneumatic Transducer to W7750C.

Two 209541B Excel 10 FTT Termination Modules are required for a doubly terminated daisy-chain LONWORKS Bus segment (see Fig. 38). Refer to LONWORKS Bus Wiring Guidelines form, 74-2865 for termination module placement rules.

Step 6. Configure ControllersLONSPEC� or Care PC Software is used to configure W7750 Controllers to match their intended application. Refer to the LONSPEC� 74-2937 or Care 74-5587 User Guides for details on operating the PC software.

W7750 Controllers are shipped from the factory with a default hardware configuration. On power-up, the controller configuration parameters are set to the default values listed in

Table 20 in Appendix C. The controller can operate normally in this mode (if the equipment and wiring match the default setup), and given valid sensor inputs, the outputs are controlled appropriately to maintain space temperature at the default setpoint. The default I/O arrangement for the W7750A is printed on the terminal labels. Also see the wiring details in Fig. 27 in Step 4, Prepare Wiring Diagrams. The labeled I/O terminals are defined in Table 10.

Step 7. Troubleshooting

Troubleshooting Excel 10 Controllers and Wall ModulesIn addition to the following information, refer to the Installation Instructions and Checkout and Test manual for each product. Most products have a Checkout and Test section in their Installation Instructions manual. If not, look for a separate Checkout and Test manual. See the Applicable Literature section for form numbers.

1. Check the version numbers of the controller firmware.2. Check the wiring to the power supply and make sure

there is a good earth ground to the controller.3. Check the occupancy and HVAC modes.

4. Compare the current actual setpoint with the actual space temperature.

5. Check the desired configuration settings.6. Check the network wiring and type of wire used.7. Check the bindings and referred points.

NOTE: If the fan shuts off periodically for no specific reason and the controller restarts the fan by itself after about 20 to 60 seconds, the cause could be a bad Air Flow switch. If the controller has a digital input assigned as a Proof of Air Flow input, try unconfiguring this digital input to see if these shutdowns continue. If not, adjust or replace the Air Flow switch to get it working.

NOTE: The node can be reset by switching the node to MANUAL and then to the normal operating mode (see Fan Operation in Appendix B).

Also, the Excel 10 variables, AlarmLogX where X is 1 through 5, that store the last five alarms to occur in the controller, are available. These points can be viewed through LONSPEC� LONSTATION� or Care.

Certain alarm conditions are suppressed conditionally as follows:

Broadcasting the Service MessageThe Service Message allows a device on the LONWORKS Bus to be positively identified. The Service Message contains the controller ID number and, therefore, can be used to confirm the physical location of a particular Excel 10 in a building.

There are three methods of broadcasting the Service Message from an Excel 10 W7750 Controller. One uses a hardware service pin button on the side of the controller (see Fig. 41). The second uses the wall module pushbutton (see

Fig. 43 and 44). By pressing the wall module pushbutton for more than four seconds, the controller sends out the Service Message. The third involves using the PC Configuration tool, as follows.

When an Assign ID command is issued from the commissioning tool, the node goes into the SERVICE_MESSAGE mode for five minutes. In the SERVICE_MESSAGE mode, pressing the Occupancy Override button on the remote wall module (refer to Fig. 43 and 44 for override button location) causes the Service Message to be broadcast on the network. All other functions are normal in the SERVICE_MESSAGE mode. Even if an Excel 10 W7750 Controller does not have an Override button connected, it can broadcast the Service Message on the network by temporarily shorting the Controller Bypass Input terminal to the Sensor Ground terminal on the W7750A,B,C (short terminals 3 and 5).

The LONSPEC� or Care PC tool is used to perform the ID Assignment task.

APPENDICES

Appendix A: Using LONSPEC�/Care to Commission a W7750 ControllerNOTE: When commissioning a CVAHU W7750 Controller,

the PC tool first checks that the actual hardware model (such as W7750A,B,C) is the same type which was selected from the Application Selection/Output tab. If the types do not match, the download does not occur and the user-entered values in the Application Selection screens all revert back to default values.

Sensor CalibrationThe space temperature, the optional resistive and voltage/current (W7750B,C only) inputs can all be calibrated. The wall module setpoint potentiometer can not be calibrated.

Perform the sensor calibration by adding an offset value (either positive or negative) to the sensed value using LONSPEC� or Care.

When calibrating voltage/current sensors on the (W7750B,C), the offset amount entered by the user is in volts, regardless of the inputs actual engineering units. See Appendix E for information on how to derive the proper voltage value to enter as an offset during calibration.

Setting the Pid ParametersThe W7750 is designed to control a wide variety of mechanical systems in many types of buildings. With this flexibility, it is necessary to verify the stability of the temperature control in each different type of application. Occasionally, the PID parameters require tuning to optimize comfort and smooth equipment operation. This applies to the W7750A,B,C Controllers.

CVAHU Controllers are configured by LONSPEC� or Care with default values of PID parameters as shown in Appendix C Table 21. If different values for these parameters are desired, Table 13 lists some recommended values to use as a starting point. These recommended values are based on past experience with the applications and in most cases do not require further adjustment.

Table 13. Recommended Values For PID Parameters.

If the PID parameters require adjustment away from these values, use caution to ensure that equipment problems do not arise (see Important below). If any change to PID control parameters is made, the adjustments should be gradual. After each change, the system should be allowed to stabilize so the effects of the change can be accurately observed. Then further refinements can made, as needed, until the system is operating as desired.

IMPORTANTMaking large or frequent changes to PID control parameters can cause equipment problems such as short cycling compressors (if stage minimum run times were disabled in User Addresses DisMinClTime or DisMinHtTime). Other problems that can occur include wide swings in space temperature and excessive overdriving of modulating outputs.

If adjustment of PID parameters is required, use the following. In the items that follow, the term, error, refers to the difference between the measured space temperature and the current actual space temperature setpoint.

� The Proportional Gain (also called Throttling Range) determines how much impact the error has on the output signal. Decreasing the Proportional Gain amplifies the effect of the error; that is, for a given error, a small Proportional Gain causes a higher output signal value.

� The Integral Gain (also called Integral Time) determines how much impact the error-over-time has on the output signal. Error-over-time has two components making up its value: the amount of time the error exists; and the size of the error. The higher the Integral Gain, the slower the control response. In other words, a decrease in Integral Gain causes a more rapid response in the output signal.

� The Derivative Gain (also called Derivative Time) determines how much impact the error rate has on the output signal. The error rate is how fast the error value is changing. It can also be the direction the space temperature is going, either toward or away from the setpoint, and its speed�quickly or slowly. A decrease in Derivative Gain causes a given error rate to have a larger effect on the output signal.

� The Control Band is used only for discharge temperature control of modulating outputs, which includes controlling the economizer dampers, and heating and cooling valves using Cascade Control. The Control Band dictates the

span through which the discharge temperature must travel to cause the output signal to go from fully closed to fully open. Also, 10 percent of the Control Band value is the size of the deadband around the setpoint where no actuator motion occurs. For example, if controlling a cooling valve with Cascade Control enabled and with the discharge temperature within 0.1 X DaTempClCtrlBd of the discharge setpoint, there is no change in the current valve position.The smaller the Control Band, the more responsive the

control output. A larger Control Band causes more sluggish control. Be careful not to set the Control Band too low and cause large over or under shoots (hunting). This can happen if the space or discharge sensors or wiring are in noisy environments and the value reported to the controller is not stable (such that it bounces). The Control Band is used only in modulating control, and has no purpose when staged control is configured.

Appendix B: Sequences of OperationThis Appendix provides the control sequences of operation for the models of the Excel 10 W7750 CVAHU Controller. The W7750A,B,C Controllers can be configured to control a wide variety of possible equipment arrangements. Tables 14 and 15 (copied from Tables 3 and 4) summarize the available options. This Appendix provides a more detailed discussion of these options.

Common OperationsThe Excel 10 W7750 Controller applications have many common operations that are applicable regardless of the type of heating, cooling, or economizer equipment configuration. These operations are available to the W7750A and the W7750B,C Versions of the CVAHU Controller, and the I/O and network configurations for them are summarized in Table 14.

Available input options are from the wall module and the hard-wired analog and digital inputs. Each application can have only a subset of these devices configured based on the number of physical I/O points available. However, some of the inputs are available over the LONWORKS Bus network.

NOTE: Each W7750 Controller must have a space temperature sensor input either wired directly to the controller, or shared from another LONWORKS Bus device, and must have a digital output configured for controlling the supply fan. In addition, if modulating economizer control is desired, a discharge air temperature sensor must be physically connected to the Excel 10 W7750 Controller. A discharge temperature signal cannot be brought into the controller through the LONWORKS Bus network.

than Intermittent Fan (see Fan Operation in this Appendix), and the mode is Occupied when the RmTemp value becomes invalid, the fan continues to run.

REMOTE SETPOINT (RmtStptPot)

NOTE: Unocc heat and cool setpoints cannot be changed without the pc tool.

This is the Setpoint Potentiometer contained in the T7770 or the T7560A,B Wall Module. When configured, this occupant value is set to calculate the actual cooling or heating Occupied Setpoint. There are two options for how to calculate the actual setpoint to be used by the temperature control algorithm: (Offset) and (Absolute Middle). When SetPtKnob is set to Offset, the Wall Module setpoint knob represents a number from -9° to +9°F (-5° to +5°C) which is added to the software occupied setpoints for the heat and the cool modes (CoolOccSpt and HeatOccSpt). When SetPtKnob is set to Absolute Middle, the setpoint knob becomes the center of the Zero Energy Band (ZEB) between the cooling and heating occupied setpoints. The size of the ZEB is found by taking the difference between the software heating and cooling occupied setpoints; therefore, for Absolute Middle, the actual setpoints are found as follows:

ActualCoolSpt = RmtStptPot + (CoolOccSpt - HeatOccSpt) / 2

ActualHeatSpt = RmtStptPot - (CoolOccSpt - HeatOccSpt) / 2

During Standby and Unoccupied times, the remote setpoint pot is not referenced, and the software setpoints for those modes are used instead.

SETPOINT LIMITS (LoSetptLim AND HiSetptLim)Remote setpoint pot limits are provided by LoSetptLim and HiSetptLim. The occupied setpoints used in the control algorithms are limited by these parameters. When the setpoint knob is configured to be of type Absolute Middle, the lowest actual setpoint allowed is equal to LoSetptLim, and the highest actual setpoint allowed is equal to HiSetptLim. When the setpoint knob is configured to be an Offset type, the lowest actual setpoint allowed is equal to HeatOccSpt - LoSetptLim, and the highest allowed is equal to CoolOccSpt + HiSetptLim.

BYPASS MODE (StatusOvrd AND StatusLed)During Unoccupied periods, the facility occupant can request that Occupied temperature control setpoints be observed by depressing the Bypass pushbutton on the wall module. When activated, the controller remains in Bypass mode until:

1. Bypass Duration Setting has timed out (BypTime), or2. User again presses the Wall Module pushbutton to

switch off Bypass mode, or3. Occupancy schedule (DestSchedOcc network input or

TimeClckOcc digital input) switches the mode to Occupied.

4. User sets the DestManOcc network point to Not Assigned.

The LED on the T7770 Wall Module (Override LED) indicates the current bypass mode status (see the T7770C,D Wall Module Bypass Pushbutton and Override LED section). The LCD on the T7560 Digital Wall Module indicates the current bypass mode status (see the T7560A,B Digital Wall Module Bypass Pushbutton and LCD Occupancy Symbols section).

BypassTimeBypassTime is the time between the pressing of the override button at the wall module (or initiating OC_BYPASS via nviManOcc) and the return to the original occupancy state. When the bypass state has been activated, the bypass timer is set to BypassTime (default of 180 minutes).

OverrideTypeOverrideType specifies the behavior of the override button on the wall module. There are three possible states that have the following meanings:

NONE disables the override button.NORMAL causes the override button to set the OverRide

state to OC_BYPASS for BypassTime (default 180 minutes), when the override button has been pressed for approximately 1 to 4 seconds, or to set the OverRide state to UNOCC when the button has been pressed for approximately 4 to 7 seconds. When the button is pressed longer than approximately 7 seconds, then the OverRide state is set to OC_NUL (no manual override is active).

BYPASS_ONLY causes the override button to set the OverRide state to OC_BYPASS for BypassTime (default 180 minutes), on the first press (1 to 7 seconds). On the next press, the OverRide state is set to OC_NUL (no manual over ride is active).

OverridePriorityOverridePriority configures the override arbitration between nviManOcc, nviBypass.state, and the wall module override button. There are two possible states which have the following meanings:

LAST specifies that the last command received from either the wall module or nviManOcc determines the effective override state.

NET specifies that when nviManOcc is not OC_NUL, then the effective occupancy is nviManOcc regardless of the wall module override state.

CYCLES PER HOUR (ubHeatCph AND ubCoolCph)ubHeatCph specifies the mid-load number of on / off cycles per hour (default is 6), when the mode is HEAT. ubCoolCph specifies the mid-load number of on / off cycles per hour (default is 3), when the mode is COOL. This is to protect the mechanical equipment against short cycling causing excessive wear. In addition the cycle rate specifies the minimum on and off time according to Table 17.

T7770C,D OR T7560A,B WALL MODULE BYPASS PUSHBUTTON OPERATIONThe Wall Module Bypass pushbutton is located on both the T7770C,D or the T7560A,B Wall Modules, see Fig. 43 and 44. The bypass pushbutton can change the controller into various occupancy modes, see Table 16.

NOTES: If the pushbutton is held down for longer than seven seconds, the controller reverts back to No Override and repeats the cycle above. See Fig. 45.

Continuous Occupied override mode can only be initiated remotely; that is, over the LONWORKS Bus network.

Fig. 45. LED and Bypass pushbutton operation.

STANDBY MODE (StatusOcySen)The digital input for an occupancy sensor (usually a motion detector or possibly a time clock) provides the controller with a means to enter an energy-saving Standby mode whenever people are not in the room. Standby mode occurs when the scheduled occupancy is Occupied, and the occupancy sensor detects no people currently in the room (digital input contacts Closed means people are in the room, and contacts Open means the room is Unoccupied). When in Standby mode, the Excel 10 W7750 Controller uses the Standby Cooling Setpoint for cooling (CoolStbySpt), or the Standby Heating Setpoint for Heating (HeatStbySpt) as the Actual Space Temperature Setpoint. The occupancy sensor signal can also be a network input from another LONWORKS Bus device, so that no physical sensor is required at the receiving W7750 Controller.

IMPORTANTWhen the W7750 Controller is in Standby mode, the economizer minimum position setting is not observed. This means the fresh air dampers will go fully closed if there is no call for cooling.

CONTINUOUS UNOCCUPIED MODEThis mode is entered when a wall module is configured with a Bypass pushbutton that was pressed for four to seven seconds causing the wall module LED/LCD to blink. This mode can also be entered via a network command (ManualOcc set to Unoccupied). If the controller is in this mode, it reverts to the Unoccupied setpoints for temperature control, and the economizer does not observe its minimum position setting. The controller remains in this mode indefinitely until the Bypass pushbutton is pressed to exit the mode or a network command is sent to clear the mode. A configuration parameter is available to disable wall-module initiation of Continuous Unoccupied mode (OvrdType).

OCCUPANCY MODE AND MANUAL OVERRIDE ARBITRATIONThe W7750 has multiple sources for occupancy schedule information and, therefore, it employs an arbitration scheme to determine the current actual mode. Time-of-day (TOD) schedule status comes from two sources, a configured digital input for OccTimeClock or the DestSchedOcc network input received from a central control. If the digital input source is configured, it has highest priority and determines the Occupancy mode. This digital input is either ON (shorted = occupied), OFF (open = unoccupied), or not active (not configured); otherwise, the status is determined by the DestSchedOcc input from the network source. The DestSchedOcc has three possible states, occupied, unoccupied or standby.

Manual Override Status can be derived from three sources and governed by two selectable arbitration schemes. The two schemes are:� Network Wins or Last-in Wins, as set in OvrdPriority.

The three sources of manual override status are:DestManOcc - Has possible states: Occupied,

Unoccupied, Bypass, Standby and Not Assigned (not active). This input source has the highest priority in determining manual override status for a Network Wins arbitration scheme, and in the event there is more than one source change at a time in the Last-in Wins arbitration scheme. Here, bypass initiates a self-timed bypass of the control unit and expires upon completion of the defined timed period. The controller then treats the bypass status of this input as Not Assigned until the next change in status.

DestBypass - Has possible states: Bypass On, Bypass Off or Not Assigned (not active). This input places the controller in an untimed bypass state or turns off the bypass mode. This source is second in priority to DestManOcc under the same arbitration schemes mentioned above.

Override Button -The wall module Override pushbutton can command status of Bypass, Continuous Unoccupied and Not Assigned. This source has the lowest priority status in the above mentioned schemes. The above mention sources of override must be either Not Assigned or Off before the Override pushbutton affects the manual override status in the Network Wins scheme. All actions, in this case, taken from the Override pushbutton are locked out.

Bypass status is a controller-timed event whose duration is set in BypTime. Upon expiration of the timer, the status returns to Not Assigned. The status of this input can be overridden with the receipt of Not Assigned from DestManOcc. This, in effect, cancels a timed bypass or a continuous unoccupied mode.

The Override pushbutton can be configured as Normal (all of the above mentioned states are possible), Bypass Only (Bypass and Not Assigned only) or None (effectively Disabling the Override pushbutton).

TIME CLOCK (Occ_Time_Clock)OccTimeClock is the state of the digital input configured and wired to a time clock. When the digital input is detected to be Closed (Occupied), the scheduled occupancy will be OC_OCCUPIED. If the detected state of the digital input is Open (Unoccupied), then the scheduled occupancy will be OC_UNOCCUPIED. If the Occ_Time_Clock is not configured, then either the DestSchedOcc network input received from a central control or the time clock that is broadcast from a Sched_Master configured W7750, controls the occupied mode.

SCHEDULE MASTER (Sched_Master)Sched_Master is the state of a digital input that is configured and wired to the W7750. If the Sched_Master input is closed (input shorted), the node is the schedule master and the state of the locally connected time clock will be broadcast out over the LONWORKS Bus to the other W7750 controllers. If the Sched_Master input is open, then the node is not a schedule master and the local time clock will not be sent out over the LONWORKS Bus even if the time clock input is configured. However, the DestSchedOcc network input received from a central control has a higher priority than the local time clock, and therefore overrides the local time clock. The W7750 controllers automatically bind without the need for a configuration tool.

SETPOINT RAMPINGThe W7750 Controller incorporates a ramping feature that gradually changes the space setpoints between occupancy modes. This feature is only operational if the network variable inputs DestSchedOcc, TodEventNext, and Time Until Next Change Of State (TUNCOS) are being used to change the W7750 Occupancy mode. The applicable Setpoints are OaTempMinHtRamp, OaTempMaxHtRamp, MinHtRamp and MaxHtRamp (for HEAT mode operation), and OaTempMinClRamp, OaTempMaxClRamp, MinClRamp and MaxClRamp (for the COOL mode operation). See Fig. 46 for a pictorial representation of how these setpoints interact.

During recovery operation, the setpoint changes at a rate in degrees per hour depending on the outdoor air temperature. If there is no outdoor air temperature sensor available, then MinHtRamp is used as the recovery rate.

Fig. 46. Setpoint ramping parameters with ramp rate calculation.

NOTE: Recovery ramping applies between scheduled heating or cooling setpoint changes from UNOCCUPIED to STANDBY, UNOCCUPIED to OCCUPIED, and STANDBY to OCCUPIED. Scheduled setpoint changes from OCCUPIED to UNOCCUPIED or OCCUPIED to STANDBY do not use a ramped setpoint but instead use a step change in setpoint. Recovery ramps begin before the next scheduled occupancy time and are ramped from the setpoint for the existing scheduled occupancy state to the setpoint for the next occupancy state.

RECOVERY RAMPING FOR HEAT PUMP SYSTEMSWhen the node is controlling heat pump equipment, during the recovery ramps, the heating setpoint is split into a heat pump setpoint (for compressors) and an auxiliary heat setpoint (for auxiliary heat stages). The heat pump setpoint is a step change at the recovery time prior to the OCCUPIED time. Recovery time is computed from the configured heat recovery ramp rate. The recovery time is calculated:Recovery time = (OCC setpoint - current setpoint)/ramp rate

See Fig. 47 for the various setpoints.

Fig. 47. Setpoint ramping parameters with setpoint calculation.

During the COOL recovery period, the setpoint changes at a rate in degrees per hour relative to the outdoor air temperature. If there is no outdoor air temperature sensor available, the MinClRamp is used as the recovery rate.

See Fig. 48 for the various setpoints.

Fig. 48. Setpoint ramping parameters with ramp rate calculation.

NOTES: The setpoint used during the COOL recovery period is similar to the heat mode in Fig. 46, except the slope of the line reverses for cooling.

Recovery ramping applies between scheduled heat-ing or cooling setpoint changes from UNOCCUPIED to STANDBY, UNOCCUPIED to OCCUPIED, and STANDBY to OCCUPIED. Scheduled setpoint changes from OCCUPIED to UNOCCUPIED or OCCUPIED to STANDBY do not use a ramped set-point, but instead, use a step change in setpoint. Recovery ramps begin before the next scheduled occupancy time and are ramped from the setpoint for the existing scheduled occupancy state to the set-point for the next occupancy state.

FAN OPERATIONThe W7750 supply fan can be controlled in one of two different ways. In Continuous Fan mode, the fan runs whenever the controller is in Occupied mode. When in Standby or Unoccupied modes, the fan cycles on with a call for cooling (or heating if the FanOnHtMode parameter is set). In Intermittent Fan mode, the fan cycles on with a call for cooling (or heating if the FanOnHtMode parameter is set), and cycles off when the space temperature control is satisfied.

The fan control supports an optional (Proof of Air Flow) digital input, that allows monitoring of the supply fans status. If the fan is commanded on, the Proof of Air Flow digital input is checked up to three times to verify that the fan is running after an initial delay of FanOnDelay seconds (adjustable). If the fan fails to start the CVAHU must be reset by first cycling CVAHU power. If this does not work, set DestManMode to Manual and then back to Enable. After a reset the application restarts�all outputs switch off and auto control is enabled.

Also, the W7750 Controller provides fan-run-on operation that keeps the fan running for a short time after heating or cooling shuts off. The amount of time that the fan continues to run is set in FanRunOnHeat for heating mode and FanRunOnCool for cooling mode.

WINDOW SENSOR (StatusWndw)The digital input for a window contact provides the algorithm with a means to disable its temperature control activities if someone has opened a window or door in the room. When a window is detected to be Open (digital input contacts Open equals window open), the normal temperature control is disabled, and the W7750 Controller enters the Freeze Protect mode. Freeze Protect mode sets the space setpoint to 46.4 °F (8°C) and brings on the fan and heat if the space temperature falls below this setpoint. Normal temperature control resumes on window closure. The Window sensor signal can also be a network input from another LONWORKS Bus device, so that no physical sensor is required at the receiving W7750 Controller.

SMOKE CONTROLThe Excel 10 W7750 Controller supports three smoke-related control strategies:

1. Emergency Shutdown (all outputs off).2. Depressurize (fan on, outdoor air damper closed).3. Pressurize (fan on, outdoor air damper open).

The controller is placed in one of these three control states whenever the W7750 mode becomes SMOKE_EMERGENCY, which can be initiated via a network command (DestEmergCmd) or from a local (physically connected) smoke detector digital input. When in SMOKE_EMERGENCY mode, the W7750 Controller uses the control strategy found in SmkCtlMode (one of the three listed above), and the normal temperature control function is disabled. If a W7750 local smoke detector trips, the SrcEmerg network variable (for other LONWORKS Bus devices to receive) is set to the Emergency state.

DEMAND LIMIT CONTROL (DLC)When The LONWORKS Bus network receives a high-electrical-demand signal, the controller applies a DlcBumpTemp amount to the current actual space temperature setpoint value. The setpoint is always adjusted in the energy-saving direction. This means that if the W7750 Controller is in Cooling mode, the DLC offset bumps the control point up, and when in Heating mode, bumps the control point down.

DIRTY FILTER MONITORThe air filter in the air handler can be monitored by the W7750 and an alarm issued when the filter media needs replacement. The two methods of monitoring the filter are:

1. A differential pressure switch whose contacts are con-nected to a digital input on the W7750A or W7750B,C; and

2. A 2 to 10V differential pressure sensor wired to a current input on the W7750B,C. If the analog input sensor is used, its measured value 0 to 5 in. w.c. (0 to 1.25 kPa) is compared to a user-selectable setpoint (FltrPressStPt�valid range: 0 to 5 in. w.c. (0 to 1.25 kPa)), and the Dirty Filter alarm is issued when the pressure drop across the filter exceeds the setpoint.

START-UPSTART_UP_WAIT is the first mode after application restart or power-up. During START_UP_WAIT, the analog and digital inputs are being read for the first time, no control algorithms are active, and the physical outputs (fan and heat/cooling stages) are in the de-energized position. The node remains in

the START_UP_WAIT mode for a pseudo-random period (depending on neuron_id) between 12 and 22 seconds and then transitions to one of the operating modes, depending on the inputs that are read from the physical and network inputs. The pseudo random period prevents multiple controllers from simultaneously starting major electrical loads when power is restored to a building.

NOTES: After a controller download via LONSPEC�/Care, the delayed reset time is bypassed and the controller starts after a 40-second initialization.

Not all network inputs can be received during the START_UP_WAIT period because many network variables are updated at a slower rate; therefore some control decisions can be considered tempo-rarily inappropriate.

Temperature Control OperationsSee Fig. 49 for a diagram of a typical W7750 Unit.

STAGED COOLING CONTROLThe Excel 10 W7750 Controller supports up to four stages of D/X cooling. As space temperature rises above the current

Cooling Setpoint, the controllers mode of operation is switched to the COOL mode. When in the COOL mode, all heating outputs are driven closed or off (with the exception

that occurs during IAQ Override Operation, see above), and the staged cooling outputs are enabled for use. When in the COOL mode, the PID cooling control algorithm compares the current space temperature to the EffectiveCoolSetPt, and calculates a PID error signal. This error signal causes the cooling stage outputs to be cycled as required to drive the space temperature back to the setpoint. Fig. 50 illustrates the

relationship between PID error and staged output activity. As the error signal increases and the space temperature is getting farther away from setpoint, or is remaining above setpoint as time elapses, additional stages of cooling are energized until, if PID error reaches 100 percent, all configured stages are on.

Fig. 50. Staged output control versus PID Error.

If economizer dampers are configured, and the outdoor air is suitable for free cooling, the economizer operates as the first stage of cooling. For example, if a controller was configured with two stages of mechanical cooling and an economizer, the application should be viewed in Fig. 50 as a three-stage system.

Setpoints for the PID gains allow for unit-by-unit adjustment of the control loop, if required; however, any change from the default values should be minimal.

The PID control algorithm used to control staged cooling is anticipator-driven, and is similar to the algorithm used in the T7300 commercial thermostat. All staging events are subject to a minimum interstage time delay, which is based on the cycles per hour user setting (CoolCycHr). The minimum interstage time delay ranges from 90 seconds (at 12 cycles per hour) to 8.5 minutes (at two cycles per hour), see Table 17. The user has the option to disable the minimum run timer (DisMinClTimer for cooling). If the minimum run timer is disabled, the interstage time delay is fixed at 20 seconds. The cycling rate is separately selectable for heating and cooling between 2 and 12 cycles per hour (cph).

STAGED HEATING CONTROLThe Excel 10 W7750B,C Controller supports up to four stages of heating.

When in the HEAT mode, the PID cooling control algorithm compares the current space temperature to the EffectiveHeatSetPt, and calculates a PID error signal.

outputs to be cycled, as required, to drive the space temperature back to the Setpoint. Fig. 50 illustrates the relationship between PID error and staged output activity.

As the error signal increases, the space temperature gets further away from the setpoint, or is remaining below the setpoint as time elapses, additional stages of heating are energized until, if PID error reaches 100 percent, all configured stages are on.

The PID control algorithm used to control staged heating is anticipator-driven, and is similar to the algorithm used in the T7300 commercial thermostat. All staging events are subject to a minimum interstage time delay, that is based on the cycles per hour user setting (HeatCycHr). The minimum interstage time delay ranges from 90 seconds (at 12 cycles per hour) to eight minutes (at two cycles per hour). See Table 17. The user has the option to disable the minimum run timer for heating (DisMinHtTimer). If the minimum run timer is disabled, the interstage time delay is fixed at 20 seconds. The cycling rate is separately selectable for heating and cooling between two and 12 cycles per hour (cph).

Setpoints for the PID gains allow for unit-by-unit adjustment of the control loop, if required; however, any change from the default values should be minimal.

CASCADE CONTROL OF MODULATING COOLING/HEATINGThe Excel 10 W7750 Controller supports modulating cooling and heating valves. These valves can be controlled directly from the space temperature (like the staged control) or, if the CascCtrl flag is set, they are modulated to maintain the discharge air temperature at its setpoint. The discharge air setpoint is calculated based on the space temperature deviation from the space setpoint. This is commonly called cascade control. In the W7750 Controller, cascade control is available for use with PWM (W7750B,C only) and Series 60 modulating heating and cooling, but not for use with staged heating/cooling.

Setpoints for the PID gains and for the control band allow for unit-by-unit adjustment of the control loops, if required; however, any change from the default values should be minimal. Also, the W7750 Controller uses an adaptive algorithm (patent pending) to continuously assess the validity of the calculated discharge setpoint, and adjust it, as needed, to ensure precise, accurate control.

SERIES 60 MODULATING CONTROLSeries 60 Control is also commonly referred to as Floating Control. The Excel 10 W7750A,B,C Controllers can drive Series 60 type actuators (economizer only for W7750A) to control a modulating cooling valve, a heating valve, and economizer dampers. When floating control is used, the full-stroke motor drive time of the actuator must be entered into the configuration parameter CoolMtrSpd (for cooling), HeatMtrSpd (for heating), or EconMtrSpd (for the economizer dampers).

PULSE WIDTH MODULATING (PWM) CONTROLThe Excel 10 W7750B,C Controllers can drive a PWM-type actuator to control a modulating cooling valve, a heating valve, and economizer dampers. PWM control positions the actuator based on the length, in seconds, of the pulse from the digital output. The controller outputs a pulse whose length consists of two parts, a minimum and a maximum. The minimum pulse time represents the analog value of zero

percent (also indicates a signal presence) and the maximum pulse length that represents an analog value of 100 percent. If the analog value is greater than zero percent, an additional time is added to the minimum pulse time. The length of time added is directly proportional to the magnitude of the analog value. If PWM control is used, the configuration parameters for the PWM operation must be specified. These are PwmPeriod, PwmZeroScale, and PwmFullScale. These three parameters are shared by all configured PWM outputs; this means the heating, cooling, and economizer actuators must be configured to accept the same style of PWM signal.

Example: To find the pulse width of a valve actuator (for example stroke mid position - 50 percent) with the PwmZeroScale = 0.1 seconds, PwmFullScale = 25.5 seconds, and the PwmPeriod = 25.6 seconds. There are 256 increments available, so the number of increments required for 50 percent would be (0.5 X 256) or 128. The time for each increment for this industry standard pulse time is 0.1 seconds. The pulse width is the minimum time (0.1 second) + the number of increments (128 times the (0.1 second) plus 0. 1) = 12.9 seconds. The W7750B,C Controllers would command the valve output on for 12.9 seconds for the PwmPeriod of 25.6 seconds to maintain the valve position at 50 percent.

OUTDOOR AIR LOCKOUT OF HEATING/COOLINGA mechanism is provided in the W7750 to disable the heating equipment if the outdoor air temperature rises above the OaTempHtLkOut setpoint. Similarly, the cooling equipment is disabled if the outdoor air temperature falls below the OaTempClLkOut setpoint. The algorithm supplies a fixed 2°F (1.1°C) hysteresis with the lock-out control to prevent short cycling of the equipment.

ECONOMIZER DAMPER CONTROLA mixed-air economizer damper package can be controlled to assist mechanical cooling in maintaining the discharge air at setpoint. Therefore, if modulating economizer damper control is desired, a discharge air temperature sensor is required. If the outdoor air is not currently suitable for cooling use (see the Economizer Enable/Disable Control section), the outdoor air damper is held at the adjustable minimum position (EconMinPos) for ventilation purposes.

Because the outdoor air can be used to supplement mechanical cooling, the economizer operates as if it were the first stage of cooling. So, if the outdoor air is suitable for cooling use, the mechanical cooling (either staged or modulating) is held off until the economizer has reached its fully open position. Then, if the discharge temperature continues to be above setpoint, the mechanical cooling is allowed to come on. If the outdoor air is not suitable for cooling use, the economizer is set to its minimum position, and mechanical cooling is allowed to come on immediately.

When the controller is in the Heat mode, the economizer is held at the minimum position setting (EconMinPos). The minimum position setting is only used during Occupied mode operation. When in Standby or Unoccupied modes, the outdoor air dampers are allowed to fully close if there is no call for cooling, or if the outside air is not suitable for cooling use.

INDOOR AIR QUALITY (IAQ) OVERRIDEThe Excel 10 W7750 Controller supports an IAQ override feature that upon detection of poor air quality in the space, allows the economizer dampers to be opened above the standard minimum position setting to a value set in


74-2958�2 62

EconIAQPos. Two different methods of detecting poor air quality are supported, The first is by using an IAQ switch device connected to a digital input on the W7750 Controller, where a contact closure indicates poor air quality and initiates the IAQ override mode. The second, which is only available on the W7750B,C is through an analog input that connects to a CO2 Sensor (0 to 10V), such as the C7232A,B or C7632A,B. The measured value of CO2 from this sensor (0 to 2000 ppm) is compared to the setpoint IAQSetpt. When the CO2 level is higher than the setpoint (800 PPM), the IAQ override is initiated. The IAQSetpt hysteresis is 50 PPM, IAQ override is deactivated at a CO2 level less than 750 PPM.

When the W7750 Controller is in the COOL mode during an IAQ override, it is possible for the heating outputs to be activated. This can occur if the outdoor air temperature is cold enough to cause the discharge air temperature to drop below the DaTempLoLim setpoint when the dampers open to the EconIAQPos position, and the IaqUseHeat flag is set. If this situation occurs, the heating is controlled to maintain the discharge air temperature at 1°F (0.65°C) above the DaTempLoLim setpoint.

FREEZE STATUpon receiving a contact closure, the W7750 control algorithm will close the outdoor air damper and open the hot water and chilled water valves (if available) to the full open position as a safety precaution. If manual-reset operation is desired, the Freeze Stat device must provide the physical pushbutton, which the operator presses, to reset the system after a freeze condition has occurred.

DISCHARGE AIR LOW LIMIT CONTROLIf the discharge air temperature falls below the adjustable discharge air low limit setpoint (DaTempLoLim), an alarm is issued, and the outdoor air damper is driven below the minimum position setting until the discharge temperature is up to the low limit. If necessary, the damper can go completely closed even during Occupied mode operation. As the discharge temperature warms up, the economizer modulates open until the minimum position setting is reached. At this point, the low limit alarm is cleared.

ECONOMIZER ENABLE/DISABLE CONTROLThe W7750 Controller has inputs to determine if the outdoor air is suitable to augment cooling. The economizer dampers can be enabled/disabled for using outdoor air as the first stage of cooling based on one of ten allowable strategies:

1. Digital Input Enable/Disable�contact closure enables economizer.

2. Outdoor Temperature�when the outdoor temperature is less than OaEconEnTemp, then the outdoor air is suitable to augment cooling.

3. Outdoor Enthalpy, Type A�when the outdoor enthalpy meets the W7212 type A requirements, the outdoor air is suitable to augment cooling. See Fig. 57 and 58.

4. Outdoor Enthalpy, Type B�when the outdoor enthalpy meets the W7212 type B requirements, the outdoor air is suitable to augment cooling. See Fig. 57 and 58.

5. Outdoor Enthalpy, Type C�when the outdoor enthalpy meets the W7212 type C requirements, the outdoor air is suitable to augment cooling. See Fig. 57 and 58.

6. Outdoor Enthalpy, Type D�when the outdoor enthalpy meets the W7212 type D requirements, the outdoor air is suitable to augment cooling. See Fig. 57 and 58.

7. Differential Temperature�the difference between outdoor temperature and return air temperature is compared to DiffEconEnTemp to determine whether outdoor air or return air is more suitable for use to augment mechanical cooling.

8. Single Calculated Enthalpy�the calculated outdoor enthalpy in btu/lb is compared to the enthalpy setpoint (OaEnthEn) in btu/lb, and the outdoor temperature is compared to the outdoor temperature limit setpoint (OaEconEnTemp) for a high limit. The compared difference determines whether outdoor air is suitable for use to augment mechanical cooling.

9. Differential Enthalpy, Either Sensed or Calculated�the difference between outdoor enthalpy and return air enthalpy determines whether outdoor air or return air is more suitable to augment mechanical cooling. When enthalpy sensors are configured, they are used for comparing enthalpy. If no enthalpy sensors are available, then enthalpy is calculated using outdoor and return air humidity and temperature sensors. The switching differential is fixed at 1.0 mA for enthalpy sensors, and 0.25 btu/lb for calculated enthalpy.

NOTE: If no return temperature sensor is configured, space temperature is used to calculate return air enthalpy.

10. Network Enabled�the network input DestEconEnable controls the enabling and disabling of the economizer. When using the network input, select Econo Enable Type: No Economizer in E-Vision. The network input has priority over the other nine economizer control selections.

Table 19. Engineering Units For Analog Points.

All of the NvName values that are stored in EEPROM memory have a prefix of nci.

NOTE: These parameters are stored in EEPROM and are limited to 10,000 writes. Do NOT use them as outputs from Control Strategies, Time Programs, or Switching Tables. If these points are changed more than 10,000 times, irreversible hardware failure results

Tables 20 through 28 provide point attributes as follows:

EngineeringUnits� This field indicates the point valid range and

displayed Engineering Unit. For digital points, the valid states and the corresponding enumerated values are shown.

Default� The value or state of the point on controller start-up.

LONSPEC�/Care(M) Monitor� These points are viewable within the Controller

Monitoring on-line screen.(P) Parameter�These points refer to control parameters

adjustable in the Application Selection dialog boxes.

(S) Schematic�These points appear in Care monitor mode graphics.

Shareable� These points can be set up for data sharing in Command Multiple Points, Read Multiple Points, or Refer Excel 10 Points as either a data source or a destination.

Mappable� These points can be converted into a C-Bus point (XL5000) used by C-Bus devices. A mappable point has a one-to-one relationship with a C-Bus User Address.

Direct Access� These points are accessible through the

Subsystem Points mechanism in LONSPEC�/LONSTATION� or XBS - XL5000.

HardwareConfig.� These are points that involve controller I/O

configuration. Any change to Hardware Config. points causes the W7750 to perform an application reset; therefore, these points can only be modified off-line.

ManualConfig.� These points are used to set the controller

outputs when in manual mode. The W7750 is placed in manual mode through a menu selection in the LONSPEC� or Care Controller Monitor screen.

Test� These points can be controlled in LONSPEC� or Care test mode that is used for field checkout/ debuging.

Failure Detect Input Point� These points need an update periodically or a

communication alarm is generated. The failure detect mechanism is only active when the NV is bound (bindings are configured using Refer Excel 10 points). The time between the updates is adjustable.

Non-Failure Detect Input Point� These points (which are NVs that are bound or

unbound) do not check for an update periodically and do not generate an alarm.

NOTES:1. Mapped points can be viewed and changed, if

needed, through LONSPEC� or on the XI581, XI582 and XI584 C-Bus devices and on an XBS central (XL5000).

2. All Excel 10 points, mappable and calibration, configuration and internal data sharing points, can be viewed and changed, as allowed, via Direct Access (DA) mode in the LONSPEC�/LONSTA-TION� or XBS subsystem menu or via XI584.

Appendix D: XL5000 Q7750A Excel 10 Zone Manager Point Estimating GuideMemory size approximation shown below (all sizes in bytes):

When memory size is less than 110,000 bytes, the size is OK.

When memory size is between 110,000 and 128,000 bytes, the application may be too large. The user must expect to reduce the application complexity, reduce the number of attached Excel 10s or distribute the Excel 10s over more than one Zone Manager.

When memory size is greater than 128,000, the size is too large. The application size must be reduced as described above.

Approximate Memory Size Estimating Procedure.1. Determine the number of points per controller required

at the Central (for example, XBS).

NOTE: All remaining points that are not mapped can be accessed through the Direct Access feature.

2. Calculate the number of Excel 10 Zone Manager pro-gram points that are used in control logic and in the switching table.

3. Estimate the program complexity of the Zone Manager (one of three levels).a. No time programs, control logic, or switching tables.b. 10K of control logic (one time program, five

switching tables, and five control loops).c. 20K of control logic (multiple time programs, ten

switching tables, and ten control loops).Use Fig. 51 to determine the number of Excel 10s that can be connected to the Zone Manager.NOTE: More than 60 Excel 10s requires a Router.

4. Repeat for each Q7750A Excel 10 Zone Manager in a project.

Fig. 51. Point capacity estimate for Zone Manager.

The exact equation for calculating memory size follows:Memory size = 21,780+ 4096 (in case of a time program).+ CARE Control Program.+ 14 x time points x Excel 10 units.+ 50 x Excel 10 units.+ map complexity x Excel 10 units x mapped points.+ 57 x C-Bus points.+ 7488 x Excel 10 types.

Where:Time points = number of switch points in time program

per Excel 10.

Excel 10 units =number of attached Excel 10s.C-Bus points = including mapped points and others; for

example, remote points.Mapped points = number of mapped points per Excel 10,

including One-to-Many and Many-to-One mechanism.

Excel 10 types = number of different Excel 10 types (currently three)

Map complexity=20 =using One-to-Many and not using points

with read/write.30 = average.45 = many points with read/write ability.
