W6210A,D and W7210A,DSolid State Economizer Logic Module

APPLICATIONW6210A,D and W7210A,D Solid State Economizer� Logic Modules are used with solid state C7400 Enthalpy Sensors or C7650A Dry Bulb Temperature Sensors and Honeywell Series 62 and Series 72 actuators to proportion outdoor and return air dampers for economizer control in commercial HVAC equipment.

FEATURES� Operates from the cooling space thermostat to provide

a totally integrated control system.� Solid state control package provides accuracy,

reliability and stability.� Combines solid state enthalpy or dry bulb changeover

control, minimum damper position potentiometer and compressor staging relay functions.

� Optional differential enthalpy control provides greater economizer savings than single enthalpy control by selecting the most economical air for cooling. Differential enthalpy control uses two sensor inputs, one in return air and one in outdoor air then economizer control selects the air with the lower enthalpy.

� Housed in high-impact, glass-fiber reinforced plastic case.

� Enthalpy setpoint (A-D) on W6210 and W7210 Solid State Economizer Logic Module controls the combination of air temperature and humidity suitable for free cooling.

� All models include a built-in adjustable potentiometer to set minimum damper position and minimum amount of outdoor air admitted to meet minimum ventilation requirements. Terminals included for connecting optional S963B1128 Remote Minimum Position Potentiometer for remote damper control.

� LED indicates when free cooling is available.� Mount on the sheet metal duct. Mounting screws

included.� W6210A and W7210A accept inputs from discharge air

temperature sensors or mixed air temperature sensors, and C7400 Enthalpy Sensors or C7650A Dry Bulb Temperature Sensors and optional remote minimum position damper potentiometers.

� W6210D and W7210D return to mechanical cooling when outdoor air enthalpy reaches preset high limits.

for remote damper control.

Optional Applications

Remote Minimum Position ControlRemote control of outdoor air dampers is desirable when temporary additional ventilation is required. The potentiometer in the W6210/W7210 controls the minimum position of the dampers. The addition of an S963B1128 Remote Minimum Position Potentiometer allows occupants to open dampers beyond minimum position for additional ventilation. Connect the potentiometer as shown in Fig. 3.

SETTINGS AND ADJUSTMENTSPotentiometers with screwdriver adjustment slots, located on the face of the device, provide adjustments for minimum damper position and enthalpy changeover. See Fig. 4.

Fig. 4. Location of enthalpy setpoint potentiometer, minimum position

potentiometer and LED.(W7210 shown)

Adjusting Minimum Damper PositionThe minimum position potentiometer keeps the outdoor air damper from closing completely during system operation to provide ventilation.

Minimum Position Adjustment1. Disconnect mixed air sensor from terminals T and T1.2. Make sure either the factory-installed jumper is in place

across terminals P and P1 or, if remote damper position is required, that it is wired according to Fig. 3 and turned fully clockwise .

3. Connect 24 Vac across terminals TR and TR1.4. Adjust the potentiometer on the W6210/W7210 face

with a screwdriver for desired minimum position.

Outdoor Enthalpy Changeover SetpointThe outdoor enthalpy changeover setpoint returns the outdoor air damper to minimum position when enthalpy rises above its setpoint. Enthalpy setpoint scale markings, located in the W6210/W7210, are A, B, C, and D. See Fig. 6 for the corresponding control point. The factory-installed 620 ohm jumper must be in place across terminals SR and +.

Differential Enthalpy Changeover SettingDifferential enthalpy control uses two C7400 Enthalpy Sensors connected to one economizer module. The economizer compares outdoor air to the return air instead of to a set point (as with single enthalpy). Turn the setpoint potentiometer fully clockwise to the D setting. The economizer selects the lower enthalpy air (return or outdoor) for cooling for example, when outdoor air has lower enthalpy than return air, the outdoor air damper opens to bring in outdoor air for free cooling.

High Enthalpy LimitW6210D and W7210D Economizer Logic Modules have a high outdoor air enthalpy limit feature when used in differential enthalpy mode. The limit feature prevents using high enthalpy outdoor air when return air enthalpy is higher than that of outdoor air (see Table 2).

Integrated Economizer System (Fig. 5)

Operation: Single (Outdoor) EnthalpyThe purpose of an economizer is to use outdoor air for cooling, whenever possible, to reduce compressor operation.

The W6210/W7210 Economizer System, when wired as shown in Fig. 7 through 14, responds to a signal from the cooling thermostat. This system uses Solid State C7400 Enthalpy Changeover Sensor or the C7650A Dry Bulb Temperature Sensor. The C7400 responds to both dry bulb temperature and humidity, allowing use of outdoor air at

higher temperatures for free cooling when humidity is low. The C7650A responds to only dry bulb temperature and should be used only in dry, arid climates.

The economizer functions as a true first stage of cooling and provides maximum fuel economy during the cooling cycle. The economizer is automatically locked out during heating. It holds the outdoor air damper at the minimum position setting.

When the space thermostat calls for cooling, the system operates as follows:

Outdoor Air Enthalpy Is Below Setpoint1. The outdoor air damper is proportioned open (and the

return air damper is proportioned closed) to maintain between 50°F and 56°F at the mixed/discharge air sensor.

2. During economizer operation, mechanical cooling is operated by the second stage of cooling on the space thermostat.

Outdoor Air Enthalpy Is Above Setpoint1. The outdoor air damper closes to its minimum position.2. A call for cooling from the space thermostat brings on

mechanical cooling.3. During the unoccupied period, the actuator spring return

moves the outdoor air damper to the fully closed position.

NOTE: See Fig. 5 for representative locations of economizer system devices.

CHECKOUT AND TROUBLESHOOTING

CAUTIONEquipment Damage Hazard.Excessive force can damage potentiometer controls.Use a small screwdriver when adjusting enthalpy changeover and minimum damper position controls.

To check the motor, jumper T to T1 to bypass the mixed air sensor.

Use Table 4 and Fig. 21 for checkout.

Table 4. W6210A,D and W7210A,D Economizer Connected to Honeywell Actuator.

Checkout Procedure Proper Response

1. a. Disconnect power at TR and TR1. �

b. Disconnect P to P1 jumper.

c. Jumper TR to 1.

d. Jumper T1 to T.

e. If connected, remove C7400 Enthalpy Sensor from terminals SO and +. Ensure factory-installed 620 ohm resistor is connected to terminals SR and +.

� LED is off.

f. Apply power (24 Vac) to terminals TR and TR1. � Motor is in closed position.

2. Disconnect factory-installed 620 ohm resistor from terminals SR and +.

� LED turns on (A models only; for D models, go to step 3).� Motor drives toward open.

3. Simulate high and low enthalpy (single enthalpy sensor):

a. Reconnect factory-installed 620 ohm resistor across terminals SR and +.Connect 1.2K ohm 4074EJM Checkout Resistor across terminals SO and +.

�

b. Turn enthalpy setpoint potentiometer to A. � LED turns on, indicating low enthalpy.� Motor drives toward open.

c. Turn enthalpy setpoint potentiometer to D. � LED turns off, indicating high enthalpy.� Motor drives toward closed.

d. Disconnect the 1.2K ohm checkout resistor. �

4. a. To verify sensor operation, reconnect the + lead of the outdoor enthalpy sensor to the + terminal of the W6210/W7210 Economizer.

�

b. Connect a dc milliammeter between terminals SO of the W6210/W7210 and terminal S of the enthalpy sensor. (Connect the positive meter lead to terminal S of the enthalpy sensor.)

� Milliammeter indicates between 3 and 25 mA when the sensor is operating properly.

� If the milliammeter indicates zero, the sensor may be wired backward.

c. When using differential enthalpy, check the return air enthalpy sensor by connecting a dc milliammeter between terminal SR of the W6210/W7210 and terminal S or the return air enthalpy sensor. (Connect the positive meter lead to terminal S of the return air enthalpy sensor.)

� Milliammeter indicates between 3 and 25 mA when the sensor is operating properly.

� If the milliammeter indicates zero, the sensor may be wired backward.
