INTRODUCTION: WCC III SYSTEM FEATURES

__________________________________________

The question is always asked. What does the WCC III System actually do?

The WCC III system is a microprocessor-based energy management and temperature control system that is designed to minimize the energy usage of a building and maximize occupant comfort. The WCC III system provides the building owner with a means of monitoring and controlling building mechanical systems from multiple locations. The WCC III system provides computerized control of building mechanical systems and requires only basic computer experience to operate or program the system.

The following features list is part of the standard WCC III software package:

• Schedule Override by Room Number (or name)• Timed Overrides• Point Involvement Summary• Data Copy Routine• Math Operators/Enthalpy Logic• User Confi gurable Global Look Up Tables• Sliding Window Averaging of Values• Accumulation of Values• Trend Logging features which include:

Analog Trend (with graph) Analog Peak Change of State Run Time

• Multiple IP-based Operator control consoles• Proportional Reset (with graph)• Auto-Scan and Print Routines• Multiple Energy Consumption Tables (50)• Remote monitoring via IP/Internet• Local or remote override capability

• Remote read and reset• Automatic e-mail call-out on alarm (Email to Text

for Cell Phone alarm callout supported)• 16 operator codes with 4 levels of access• 365-day time clock with automatic daylight savings

time changeover• 128-week schedules and 18 holiday schedules• 8 alarm levels (5 are capable of Emailing an Alarm)• 256 Global Analogs programs• 512 Global Binaries programs• Temperature control with automatic temperature

setback• Adaptive optimized start and optimized stop• Duty cycling• Demand limiting• Dead band spreading• Lighting control

The WCC III system main components consist of a main central processing unit called a WCC III - MCD, and various types of electronic controllers that are called Satellite controllers. Some of these Satellite controllers act as an interface connection device with other types of controllers that are called TUC and RTU controllers. Equipment cost is reduced because the system, including the satellite controllers, is modular. Only the number of satellite controllers required to do the job are purchased. Installation cost is reduced because “global” information gathered at one satellite can be shared with other satellites, eliminating costly intermediate controls.

WARNING: The WCC III system is not to be used in any application where Fire/Life/Safety is an issue.

I. INTRODUCTION

WCC III Technical GuideI-2

System Features

WCC III - MCD

The acronym WCC III - MCD stands for the WattMaster Controls Center III (Version 3) - Master Communications Device, and is referred to throughout this manual as the WCC III - MCD.

The WCC III - MCD is an Internet appliance that was developed by WattMaster Controls and is an industrial-rated computer that is running the Windows® XP operating system or Linux. The WCC III - MCD provides for multiple users an access point for the various different types of WCC III operator programs and/or the tenant end-user program to connect to for remote monitoring and changing of various control setpoints. There is a program that is always running on the WCC III - MCD called BackTask.exe. This BackTask.exe program handles all of the WCC III system functions. These BackTask.exe functions include, but are not limited to, the following items:

• A MCOMM RS-485 data communications server• Internet access server• Email Server • Alarm determination• A multiple event processor and scheduler

See Section 12 for specifi c use and application of the BackTask.exe program.

See Section 13 for specifi c use and application of the WCC III - MCD.

For the WCC III - MCD to be completely functional, the WCC III - MCD is to be connected to the Internet for user access, remote alarming via Email.

The WCC III - MCD is capable of communicating with up to 239 SAT III Controllers. The WCC III - MCD considers each SAT 3C or SAT 3P as 8 controllers and each SAT 3D or SAT 3F as 4 controllers. The equivalent number of satellite controllers must be under 239.

A system with 239 satellite controllers is capable of handling up to 11472 points, with a point being defi ned as a hard-wired input or output.

NOTE: The WCC III - MCD is dedicated to the WCC III system and cannot be used for other functions. The use of hardware accessories or software programs with the WCC III - MCD that are not specifi cally approved in writing by WattMaster Controls, Inc. will void the warranty on the WCC III system. The use of software other than that furnished with the WCC III system may result in system malfunction. WattMaster Controls, Inc. is not responsible for a system failure so generated.

For the WCC III - MCD to be completely functional, the WCC III - MCD is to be connected to the internet for user access, remote e-mailing of alarms, WattMaster Controls program updates, WattMaster Controls programming, or troubleshooting assistance.

It is possible to use a network crossover cable to connect to a single WCC III operator console for user access only. This is not the recommended connection method due to lack of remote e-mailing of alarms, WattMaster Controls program updates, WattMaster Controls programming or factory troubleshooting assistance.

NOTICE: As of September 1, 2009 all WCC III - MCDs will be only be shipped with the Linux operating system installed. Older Windows XP based WCC III - MCDs should be upgraded for any future support issues from WattMaster. The Windows XP operating system is at the end of long term support with Microsoft. Microsoft’s main issues are with continuous updates, and the multitude of viruses that are written for Windows XP are also of concern.

I. INTRODUCTION


System Features

Diagram of WCC III SystemThe heart of the WCC III system consists of an Internet Appliance referred to as the Master Communications Device (WCC III - MCD) and the WCC III Operator Console which consists of a standard computer with the Windows® XP-Pro/Vista or Windows®

7 operating system, keyboard, mouse and monitor (screen). The WCC III - MCD communicates with the remote satellite controllers using a RS-485 two-wire with shield communication loop.

The WCC III - MCD connects to the Internet via cable/DSL modem/router. The WCC III - MCD can also be networked into an existing network if desired.

NOTE: WattMaster Controls does not assume responsibility for any network connections or associated networking problems. Please contract a computer network specialist for specifi c network requirements. The WCC III - MCD is only supported on Microsoft-type networks.

WCC III OPERATOR CONTROL CONSOLE COMPONENTS

The building operator control console software ( WCC3.EXE, and other associated programs) is used to monitor and control the building mechanical systems from one or more central locations, and this type of computer connection is called the WCC III Operator Control Console. The WCC III Operator Control Console consists of the following components:

1. Standard computer that is running the Windows® XP-Pro/Vista or Windows® 7 operating system.

2. Keyboard and mouse3. Monitor (LCD preferred)4. Internet access / Network5. Network or local printer (optional)

There can be multiple WCC III Operator Control Consoles, and each WCC III Operator Control Console can have multiple WCC III type programs running simultaneously with multiple connections to the WCC III - MCD. The different types of WCC III programs are as follows: WCC3.EXE, SCUSCR.EXE, WCCUTILITY.EXE, TENANTOVERRIDE.EXE, TENANTREPORT.EXE, WCC3TRENDLOG.EXE, WGCC3.EXE, WCC3GUEST.EXE, SCUSCRLtd.EXE, LimitEditor.EXE, and WCC3DOWNLOAD.EXE

WCC3.EXE (SS5021)WCC3.EXE is a user-access program. It allows for remote access via the Internet so the user or mechanical contractor may view and change data pertaining to the building’s mechanical control systems. This program provides access to the main WCC III functions, such as WEEK SCHEDULES, OPTIMAL STARTS, GLOBAL ANALOGS, GLOBAL BINARIES, OVERRIDES, and the SAT III Controller’s inputs and outputs. The viewable screens are based upon the old WCC II system screens; this was done to reduce retraining of the operator. (Access to this program is password protected.) WCC III screens are described in Section 3.

SCUSCR.EXE (SS5026)SCUSCR.exe is a user-access program. It allows for remote access via the internet so that the user or mechanical contractor may view and change data pertaining to the building’s mechanical control system. It is used mainly for control of the VAV box type controls or specialized stand-alone controllers with application-specifi c software via the interface converter that is the SAT 3C/D/F Controllers. (Access to this program is password protected.) SCUSCR.EXE screens are described in Section 4.

WCCUTILITY.EXE (SS5023)WCCUTILITY.EXE is a user-access program. It allows for remote access via the Internet so that the user or mechanical contractor may view and change data pertaining to the building’s mechanical control system. It is used mainly for Satellite save and restore, System save and restore, and copy functions. System and Alarm logs are also viewed here. (Access to this program is password protected.) The WCCUTILITY.EXE program is described in Section 5.

TENANTOVERRIDE.EXE (SS5024)TENANTOVERRIDE.EXE is a user-access program. It allows for remote access via the Internet so that the user may view and change only small amount of data pertaining to the building’s mechanical control system. It is used by a tenant or multiple tenants in the building that is being controlled by the WCC III control system. It provides a simple interface for after-hours access to the Tenant’s HVAC controls. (Access to this program is password protected.). See Section 6 for more information.

The Tenant Override Feature allows the occupants in the building to access the WCC III - MCD on the internet and cause the lights and/or heating and/or cooling equipment to control according to their occupied (daytime) control scheme. The system has the capability of overriding the control for 500 tenant overrides. The TENANTOVERRIDE.exe program is described in detail in Section 6

A summary report of which tenants used the override system is available for billing purposes. This report program is called TENANTREPORT.EXE.

TENANTREPORT.EXE (SS5025)TENANTREPORT.EXE is a user access program. It allows for remote access via the Internet so that the user or mechanical contractor may view and change data pertaining to the building’s mechanical control system. It is used for accessing and printing of after-hour tenant overrides for after-hour billing. (Access to this program is password protected.). See Section 7 for more information.

WCC3TRENDLOG.EXE (SS5028)WCC3TRENDLOG.EXE is a user access program. It allows for remote access via the Internet so that the user or mechanical contractor may view and change data pertaining to the building’s mechanical control system. It is used mainly for trend logging data that pertains to the WCC III system control points. It is a troubleshooting tool. See Section 8 for more information.

I. INTRODUCTION


WGCC3.EXE (SS5029)

WGCC3.exe is a user access program. It allows for remote access via the Internet so that the user or mechanical contractor may view and then change data pertaining to the building’s mechanical control system. It is a graphical Windows-based user’s interface and is similar in operation to the WCC3.EXE program. (Access to this program is password protected.) See Section 9 for more information.

NOTICE: As of September 1, 2009 all WCC III - MCDs will only be shipped with the Linux operating system installed. Older Windows XP-based WCC III - MCDs should be upgraded for any future support issues from WattMaster. The Windows XP operating system is at the end of long term support with Microsoft. Microsoft’s main issues are with continuous updates, and the multitude of viruses that are written for Windows XP are also of concern. The Linux operating system software on the WCC III - MCD must be maintained and updated periodically. WattMaster Controls, Inc. can do these software updates and upgrades remotely via the internet only if the WCC III - MCD is connected to the internet. This is why internet access to the WCC III - MCD is so important. Failure to keep the operating system updated could result in a WCC III - MCD system malfunction. WattMaster Controls, Inc. is not responsible for a system failure that is so generated due to lack of upgrading or updating because the end customer does not provide a static IP connection for the WCC III - MCD to the internet for WattMaster Controls to connect to.

WCC3GUEST.EXE (SS5022)WCC3GUEST.exe is a user access program. It allows for remote access via the internet but is limited and is “view only.” The user cannot make any changes so that the simple user or other non-qualifi ed personnel can view the status and data of the WCC III system. It is a companion program to the SCUSCRLTD.exe program.

SCUSCRLtd.EXE (SS5027)SCUSCRLTD.exe is a user access program. It allows for remote access via the internet, but it is limited and is “view only.” The user cannot make any changes so that the simple user or other non qualifi ed personnel can only view the status and data of the WCC III system. It is a companion program to theWCC3GUEST.exe program.

LimitEditor.EXE LimitEditor.exe is a contractor-only setup program that sets the viewable satellite limits for the SCUSCRLTD.exe program. The WCC III contractor must provide this setup fi le to the end user. The LimitEditor.exe program creates a fi le named “limit.dat” that should be located in the SCUSCRLtd subdirectory.

WCC3DOWNLOAD.EXE (SS5030)WCC3DOWNLOAD.EXE is a user-access program. It allows for remote access via the Internet so that the user or mechanical contractor may download new Satellite software. It is used only for Satellite software downloads. (Access to this program is password protected.)

Software UpdatesWCC III - MCD program updates will be made available using USB jump drives and/or Internet uploading.

NOTE: For Windows users, the end users are responsible for maintaining their system’s antivirus software. The discontinued use or non-renewal of the antivirus software that is furnished with the WCC III system may result in system malfunction. WattMaster Controls, Inc. is not responsible for a system failure so generated.

Operator Control Console Components

I. INTRODUCTION


SATELLITE TYPES The satellite controllers are fi eld mounted and then fi eld programmed. The satellite controllers are microprocessor-based units that provide direct digital control of the building’s mechanical systems. The satellite controllers receive operating instructions from the WCC III - MCD, but once they are programmed, they have the “brains” to monitor and can control the building mechanical systems independently of the WCC III - MCD. If communication from the WCC III - MCD to the satellite controllers is broken, the satellite controllers will continue to control at a predefi ned programmable “Local Set” setpoints. In the event of a short period of primary power failure, the satellites will retain both their operating instructions and accumulated data in battery backed memory.

Currently there are the following types of SAT Controllers:

• SAT III ( OE421)• SAT 3C ( OE454)• SAT 3D ( OE455)• SAT 3P ( OE455-P)• SAT 3F ( OE456)

SAT III ( OE421) - Figure I-3 (SS5003)The SAT III controller is an enhanced product upgraded replacement for the older SAT II controller that WattMaster Controls has sold for many years. The newer SAT III controller has exactly the same number of inputs and outputs that the older SAT II controller had. The older SAT II data fi le can be reused along with all of the other older WCC II data fi les. The newer SAT III controller is a drop-in functional replacement for the older SAT II controller, but the SAT III’s use requires that the WCC II front-end computer must be replaced with a WCC III – MCD. Sensors and relays etc. are wired to the SAT III controller to allow it to monitor and control loads directly. See Section 14 for specifi c use and application of the SAT III controller.

Each SAT III controller can handle the following number of inputs and outputs:

• 8 Analog Inputs with 12 bits of resolution (Can also be used as Binary Inputs)

• 16 Control Outputs (Relay N.O. Contacts)• 8 analog outputs (0-15 VDC maximum range) -

Any or all of the 8 analog outputs may be converted to Binary outputs with single additional WCC III Vout RELAY board (Relay N.O. Contacts)

I. INTRODUCTION


• 1 HSS communications port that can connect and power up as many as 5 HSS expansion type boards.

• 16 additional optional Binary Inputs by using two HSS port connected WCC III Binary Input with Time Delay board.

• 16 additional optional Binary Relay Outputs by using two HSS port connected WCC III Vout RELAY boards (Relay N.O. Contacts)

The SAT III controller has 24 LEDs on the cover of the SAT III controller. (Figure I-4)

The top 8 Status LED functions are as follows:

• SAT REC - This LED will be lit when communications are being received by the SAT III Communications Loop.

• SAT XMIT - This LED will be lit when communications are being transmitted by the SAT III Communications Loop.

• HSS REC - This LED will be lit when communications are being received from the HSS port.

• HSS XMIT - This LED will be lit when communications are being transmitted to the HSS port.

• LOCAL SET - This LED will be lit when communications with the WCC III - MCD has not occurred in at least the last two minutes. This means that the SAT III is not communicating on the SAT III communications loop. Setpoint control in the SAT III is dependent on the LOCAL SET parameters and as such is to be programmed into each control point by the user.

• STATUS 1 - This LED blinks for every 1 second if SAT III is alive.

• STATUS 2 - This LED blinks for every 1 second during power on delay, and then blinks every 8 seconds when watchdog is enabled.

• STATUS 3 - This LED blinks for every internal calculation loop completion.

The lower 16 LEDs display the status of the 16 Relay Outputs. The LEDs display the status of the eight “H” eight “C” contacts.

I. INTRODUCTION


SAT 3C ( OE454) - Figure I-5 (SS5004)The new SAT 3C controller is an advanced product replacement for the older SAT 2C controller which WattMaster Controls has sold for many years. The SAT 3C controller is 2/3 size of the older SAT 2C controller. This size change was done to reduce the overall footprint so that more controllers can fi t into a panel. The SAT 3C controller is a drop-in functional replacement for the older SAT 2C controller, but the SAT 3C’s use requires that the WCC II front-end computer be replaced with a WCC III – MCD. The SAT 3C is a version of the satellite controller that allows the WCC III - MCD to communicate with remote mounted Air Handling Unit or Roof Top Unit types of controllers called RTU-17 controllers. An RTU -17 is a microprocessor-based device that can be used to control Air Handling Units or Roof Top Units. The RTU-17 can be used as a stand-alone controller or can be used with the WCC III system.

The SAT 3C controller is basically an interface converter between the application-specifi c software that is written for the RTU-17 controller (some TUC-5Rs) and the SAT III controller software control structure. These inputs and outputs on the RTU-17s (some TUC-5Rs) are “shoe horned” into the standard SAT III control structure with the use of the SAT 3C controller. When viewing or changing the setup and operation of the application-specifi c RTU-17 controller (some TUC-5Rs), you must use the SCUSCR.EXE program to program and administer changes to these application- specifi c RTU-17 controllers. (Some TUC-5Rs) On the WCC III Satellite software control structure, the SAT 3C uses or takes the place of 8 SAT III controllers starting with address #8.

See Section 15 for specifi c use and application of the SAT 3C controller.

The SAT 3C controller has 8 status lights. The functions of these lights or LEDs are listed below.

• SAT REC - This LED will be lit when communications are being received by the SAT 3C Controller.

• SAT XMIT - This LED will be lit when communications are being transmitted by the SAT 3C Controller.

• TUC REC - This LED will be lit when communications are being received from the TUC Communications Loop.

• TUC XMIT - This LED will be lit when communications are being transmitted to the TUC Communications Loop.

• LOCAL SET - This LED will be lit when there are currently no communications with the WCC III - MCD and no communications have occurred in at least the last 2 minutes. This means that this SAT 3C communications loop is not communicating with the WCC III - MCD. All setpoint control is then dependent on the LOCAL SET parameters programmed into the SAT3 controller.

• STATUS - This LED blinks every second if SAT 3C is alive.

• “C” MODE - This LED will be lit if this Controller is programmed as a SAT 3C and blinks for every internal calculation loop completion.

• “D” MODE - This LED blinks for every second during power on delay and blinks every 8 seconds when watchdog is enabled.

Satellite Types - SAT 3D

SAT 3D ( OE455) - Figure I-6 (SS5005)The new SAT 3D controller is an advanced product replacement for the older SAT 2D controller which WattMaster Controls has sold for many years. The SAT 3D controller is 2/3 the size of the older SAT 2D controller. This size change was done to reduce the overall footprint so that more controllers can fi t into a panel. The SAT 3D controller is a drop-in functional replacement for the older SAT 2D controller, but the SAT 3D’s use requires that the WCC II front-end computer must be replaced with a WCC III - MCD. The SAT 3D is a version of the satellite controller that allows the WCC III - MCD to communicate with remote-mounted Terminal Unit Controllers ( TUC-2R , TUC-5R, and TUC-5R+).

The Terminal Unit Controller (TUC) is a microprocessor-based device which can be used to control terminal units such as pressure dependent/independent variable air volume (VAV) boxes, pressure dependent/independent fan power boxes, fan coil units, heat pumps etc. The TUC can be used as a stand-alone controller or can be used with the WCC III system.

The TUC accepts an input from a room temperature sensor to allow it to monitor the space temperature. When used with an actuator, the TUC provides pressure dependent/independent control of the primary air damper on terminal units such as variable air volume boxes, constant fan power induction units, and intermittent fan power induction units. The electronic actuator is not an integral part of the TUC-2R and must be ordered and purchased separately. The TUC-2R can also have four relay outputs to provide control of the fan and fi rst and second stages of heat on fan terminal units or to control the fan, compressor, and reversing valve on a heat pump. The TUC-2R can also provide an output to control two 24 VDC solenoid air valves to obtain “feed” and “bleed” type control of pneumatic controlled devices. The TUC is generally mounted at the terminal unit (i.e. VAV box, heat pump, etc.).

When the TUC controllers are to be used with the WCC III system, a SAT 3D satellite controller is required as the interface between the MCD and the Terminal Unit Controller (TUC). The SAT 3D is a special version of the satellite controller, and its only purpose is to interface with the TUC controllers. Up to 32 TUC controllers can be connected to one SAT 3D using a 2-wire, shielded cable. The TUC controller’s communication connections are wired to the SAT 3D controller in a “daisy chain” arrangement. That is to say, the 2-wire communications cable with shield does not have to be run from each TUC controller back to the SAT 3D controller. The 2-wire communications cable with shield is run from the SAT 3D controller to the nearest TUC controller, and the 2-wire communications cable with shield is extended from that TUC controller to the next TUC controller. The SAT 3D controller is basically an interface converter between the application-specifi c software that is written for the TUC-2R controller (Some TUC-5Rs), and the SAT III controller software control structure. These inputs and outputs on the TUC-2Rs (Some TUC-5Rs) are “shoe horned” into the standard SAT III software control structure with the use of the SAT 3D controller. When viewing or changing the setup and operation of the application-specifi c TUC-2R controller (Some TUC-5Rs) you must use the SCUSCR.EXE program to program and administer changes to these application-specifi c TUC-2R controllers. (Some TUC-5Rs) On the WCC III Satellite structure the SAT 3D uses or takes the place of 4 SAT III controllers starting with address #4.

See Section 15 for specifi c use and application of the SAT 3D controller.

Satellite Types - SAT 3F

SAT 3F ( OE456) - Figure I-7 (SS5016)The new SAT 3F controller is an advanced product replacement for the older SAT 2D controller, which WattMaster Controls has sold for many years. The SAT 3F controller is 2/3 the size of the older SAT 2D controller. This size change was done to reduce the overall footprint so that more controllers can fi t into a panel. The SAT 3F controller is a drop-in functional replacement for the older SAT 2D controller, but the SAT 3F’s use requires that the WCC II front-end computer must be replaced with a WCC III - MCD. The SAT 3F is a version of the satellite controller that allows the WCC III - MCD to communicate with remote-mounted Terminal Unit Controllers (TUC/VAVZ II).

The Terminal Unit Controller (TUC/VAVZ II) is a microprocessor-based device which can be used to control terminal units such as pressure dependent/independent variable air volume (VAV) boxes, pressure dependent/independent fan power boxes, fan coil units, heat pumps etc. The TUC/VAVZ II can be used as a stand-alone controller or can be used with the WCC III system.

When used with an actuator, the TUC/VAVZ II provides pressure dependent/independent control of the primary air damper on terminal units such as variable air volume boxes, constant fan power induction units, and intermittent fan power induction units. The electronic actuator is an integral part of the VAVZ II Controller Actuator Package and does not need to be purchased separately. The TUC/VAVZ II can also have four relay outputs to provide control of the fan and fi rst, second, and third stages of heat on fan terminal units or to control the fan, compressor, and reversing valve on a heat pump. The TUC/VAVZ II can also provide an output to control two 24 VDC solenoid air valves to obtain “feed” and “bleed” type control of pneumatic controlled devices. The TUC/VAVZ II is generally mounted at the terminal unit (i.e. VAV box, heat pump, etc.).

The SAT 3F is a special version of the satellite controller, and its only purpose is to interface with the TUC/VAVZ II controllers. Up to 16 TUC/VAVZ II controllers can be connected to one SAT 3F using a 2-wire, shielded cable. The TUC/VAVZ II controller’s communication connections are wired to the SAT 3F controller in a “daisy chain” arrangement. That is to say, the 2-wire communications cable with shield does not have to be run from each TUC/VAVZ II controller back to the SAT 3F controller.

WCC III M-Comm Board (SS5007)

The WCC III M-Comm Board is located inside of the WCC III - MCD case to provide two standard connection points for the RS-485 communications loop. Each one of these RS-485 communications loop connections can communicate with up to 60 SAT IIIControllers at distances of up to 4000 feet away from the WCC III - MCD.

To increase the number of RS-485 communications loop connections that the WCC III - MCD can have, you must use the WCC III M-Comm Loop Expansion Board. The WCC III M-Comm Loop Expansion Board provides for two additional RS-485 communications loops connections.

This WCC III M-Comm Board is a communications processor board. It uses a USB 2.0 connection for data transfer to the computer for the communication interface. The BackTask.exe program communicates to this board directly via the USB 2.0 connection. This is where the proprietary RS-485 communication packetized data that is sent and received through this board is actually packetized and unpacketized.

This WCC III M-Comm Board also serves as a connection point for the WCC III - MCD shutdown feature. The PCI buss connector is only used to obtain power (+5VDC and Ground) for this WCC III M-Comm Board.

The WCC III M-Comm Board has 5 status lights. The functions of these lights or LEDs are listed below.

• COMM 1 - This LED will be lit when SAT communications are being received by the WCC III M-Comm Board on loop 1.

• COMM 2 - This LED will be lit when SAT communications are being received by the WCC III M-Comm Board on loop 2.

• URX - This LED will be lit when there are any USB communications being received by the WCC III M-Comm board from the WCC III - MCD CPU Board.

• UTX - This LED will be lit when there are any USB communications being transmitted by the WCC III M-Comm Board to the WCC III - MCD CPU Board.

• D5 - This LED is lit when the WCC III M-Comm Board resets the WCC III – MCD CPU Board. This command could come from the power switch on the front of the WCC III - MCD CPU Board via the WCC III Shutdown Board or from the MComm Board detection that the Backtask program is not currently running.

Accessory Boards - Power and Switchable Comm

Power and Switchable Comm Board

The Power and Switchable Comm Board was designed to be used as a central connection point for the SAT III RS-485 communications loop.

Eight push-button switches are provided to disconnect the RS-485 communications loop for troubleshooting purposes.

The RS-485 communication connections are as follows: “R” to “R”, “T” to “T”, and “SHLD” to “SHLD” or “SH”. These connections are from Satellite-type controller to Satellite-type controller. These eight push-button switches only disconnect the RS-485 communications loop. THEY DO NOT SWITCH POWER ON/OFF. See Section 19 for specifi c use and application of the WCC III Power and Switchable Comm Board.

This Power and Switchable Comm Board may also be used as a central connection point for the SAT 3C/D/F TUC communications loop.

Figure I-14: The Power and Switchable Comm Board

The RS-485 communication connections are as follows: “R” to “R”, “T” to “T”, and “SHLD” to “SHLD” or “SH”. This RS-485 communications connection is from TUC Controller to TUC Controller. But, on the SAT 3C/D/F Controller, the TUC “R” connection must be wired to the SAT 3C/D/F “T” connection, and the SAT 3C/D/F Controller “R” connection must be wired to the TUC “T” connection. This is a carry over connection method from the old SAT 2C/D Controller.

The WCC III Power and Switchable Comm Board has 9 status lights. The functions of these lights or LEDs are listed below:

• D9 - This LED will be lit any time power is applied to the WCC III Power and Switchable Comm Board.

• SW1 to SW8 - These eight LEDs will be lit any time a corresponding push button is depressed to connect the RS-485 communications to the corresponding eight communication ports.

Accessory Boards - Global Bridge

Global Bridge Board (SS5012)

The WCC II to WCC III Global Bridge Board provides a means for the new WCC III system to pass information to and from the old WCC II system.

A single WCC II to WCC III Global Bridge Board can simulate (mirror) up to 8 WCC II SAT II Controllers. A WCC II to WCC III Global Bridge can also share Global Binary and Global Analog information from WCC II to WCC III and current values of the simulated (mirrored) satellites from WCC III to WCC II. But this is a one way data fl ow for the Global data. The direction is from the WCC II system to the WCC III system. See Section 20 for specifi c use and application of the WCC III Global Bridge Board.

The WCC III Global Bridge Board has 3 status lights. The functions of these lights or LEDs are listed below:

• POWER - This LED will be lit any time power is applied to the WCC III Vout RELAY board.

• COMM - This LED will be lit when WCC III communications are being received by the Global Bridge Board.

• SAT II STAT - This LED will be lit when WCC II communications are being received by the Global Bridge Board.

Fiber Optic Converter

Introduction to Fiber OpticsIn recent years it has become apparent that fi ber-optics are steadily replacing copper wire as an appropriate means of communication signal transmission. They span the long distances between local phone systems as well as providing the backbone for many network systems. WattMaster Controls, Inc. has designed an RS-485 to Fiber Optic device to work with the WCC III communication network.

A fi ber-optic system is similar to the copper wire system that fi ber optics is replacing. The difference is that fi ber optics use light pulses to transmit information down fi ber lines instead of using electronic pulses to transmit information down copper lines.

The WattMaster Controls, Inc. Serial to Fiber Optic Converter for the WCC III system consists of two parts. The FOSTC Serial to Fiber Optic Converter and the FOSTC Serial to Fiber Optic adaptor board.

Fiber Optic Adapter BoardThe PL102334 FOSTC Fiber Optic Adapter Board provides for a two-wire, RS-485 interface to the FOSTC Fiber Optic converter for the WCC III / SAT III communications loop. It is also the power supply for the FOSTC Serial to Fiber Optic Board.

RS-485 BIAS JumpersThe RS-485 BIAS jumpers for the terminating resistors need to be ON only when there is no WCC III - MCD connected to the FOSTC fi ber optic adapter board’s SAT RS-485 communication loop.

The RS-485 BIAS jumpers for the terminating resistors need to be OFF only when there is a WCC III –MCD connected to the FOSTC fi ber optic adaptor board’s SAT RS-485 communication loop.

It is recommended that this circuit board has its own 24 VAC transformer for optimal isolation on the RS-485 side.

The LED D3 “POWER” will light when the PL102334 circuit bard has power (24VAC) applied to it.

The LED D4 “COMM” will blink with the fl ow of data to and from the RS-485 communications loop.

Fiber optic cabling has inherent resistance to EMI/RFI and transient immunity, making it ideal for industrial and utility data communication applications.

TUC/ RTU CONTROLLER BOARDS TYPES

TUC-2R Controller - ( OE320)

The TUC-2R Controller is a Terminal Unit Controller that is used to control an electronic actuator. This TUC-2R has two onboard relays, hence the -2R. These two relays are used to control the electronic actuator. The TUC-2R Controller has application- specifi c software that was written for the WCC II system, but this software also will work with the WCC III system.

There are a few different types of optional relay expansion boards for the TUC-2R that are used to add more relays and or Analog output, and these optional relay expansion boards are dependent on the application software. The most common type of WCC application software for the TUC-2R is called WCC II VAVBOX (WM software # SS5001), or the new VAV Box III (WM software # SS5010). Both of these software applications allow for software selecting of the VAVBOX type.

Please note that both pressure dependent and pressure independent versions are supported with the VAVBOX and VAV Box III software.

The following VAV box types are supported with the new WCC VAV Box III software:

• Single Duct Cooling

• Heating/Cooling Changeover

• Series Fan Powered

• Parallel Fan Powered

The new VAV Box III software may also be used in the older TUC-2R Boards (with a 32K PAL and 8K RAM). This new VAV Box III software is meant as an upgraded replacement for the older WCC II VAVBOX software, or even the older single operation VAV zone controls that are listed below:

SCR110.SDF Parallel Fan w/2 Step Heat PI PF2H

Old WCC II VAVBOX exception to the rule

WattMaster Controls did not create a new WCC II screen for the proportional hot-water reheat option. We then modifi ed the software code in the VAVBOX (Version 2.03) EPROM so that you would be able use the standard VAV BOX screen, and it would then indicate that you had one stage of heat. On the VAV BOX screen you would not be able to see the actual proportional control happening. However, the hot water valve will begin modulation when it is .5 degrees above the set point and go to 100% open at 1.5 degrees below the heating set point.

See Section 4 for specifi c use and application of the TUC-2R Controller and specifi c application software relating to the WCC III system.

TUC/RTU Controller Boards - TUC-5R/TUC-5R+

TUC-5R (TUC-5R+) Controller - ( OE330 and OE331)

The TUC-5R (later boards use the TUC-5R+) Controller is a Terminal Unit Controller that is used to control a Dual Duct, Heat Pump, or Constant Volume Air Handler. This TUC-5R has fi ve onboard relays, hence the -5R. The TUC-5R Controller has application-specifi c software that was written for the WCC II system, but this software also works with the WCC III system. There are currently no expansion boards for the TUC-5R+ that will work with the application software for the WCC III system.

Common TUC-5R+ WCC software is as follows:

TUC/RTU Controller Boards - RTU-17

RTU-17 CONTROLLER - ( OE310)

The RTU-17 Controller is typically used to control a Constant Volume Air Handler Unit. This RTU-17 has seven onboard relays, eight analog inputs, and two analog outputs. The total I/O on this board sums to seventeen, hence the -17. The RTU-17 Controller has application-specifi c software that was written for the WCC II system, but this software also works with the new WCC III system. There are currently no expansion boards for the RTU-17 that will work with the application software for the WCC III system.
