DAMPER WIRING

Wiring the SmartAire™ Power Damper:
Wire according to the below diagram and set integrated switch to Off (I).

Wiring Schematic

Testing Function of the SmartAire™ Power Damper:

• Set the integrated switch to ON and either:
• Wait 30 minutes for operation.
• Use a temporary jumper wire to connect R and Y for immediate operation. See yellow wire diagram below.
• The damper should then operate and the Dehumidifier fan should come on.
• Make sure to set integrated switch back to Off (I) after testing.
  

AHU WIRING

Synchronize the SmartAire™ Power Damper operation with the heating and cooling runtime to prevent unnecessary central fan operating time (refer to the dotted lines in the diagram).

SET UP

Setting up the unit:
When powered ON, the SmartAire™ Power Damper performs a 30-second booting sequence followed by a 30-minute period where is stays OFF, but will activate if a heating or cooling call is sent to the AHU.

Refer to local building codes to determine the required airflow.

1. Doublecheck the wiring, and turn power back ON to the AHU.

2. Set the thermostat to send a heating or cooling call, or jump R and Y on the terminal block. This will force the ventilation ON for at least 5 minutes.

3. Measure the airflow.
   If it needs adjustment, perform step 4. If the airflow does not need adjustment, go to step 5.

4. The damper is factory set to fully open position. To adjust it, set the left pot to DAMPER ADJUSTMENT to start the AHU blower, and wait 5 seconds. The LED will blink continuously to indicate the unit is in DAMPER ADJUSTMENT mode.
   While measuring the airflow, adjust the damper using the RUN TIME % pot until you’ve reached the desired value.
   

5. Select the desired mode according to the table and map on page 11. Doing so also saves the damper adjustment made in the previous step if applicable.

6. Set the RUN TIME % pot

Run time % = Required Airflow
Measured Airflow
Example:
Run Time % = 60 CFM 120 CFM

TESTING

When powered ON, the SmartAire™ Power Damper performs a 30-second booting sequence followed by a 30-minute period where it stays OFF, but will activate if a heating or cooling call is sent to the AHU.

Blower Door Test (Force the Damper Closed):
