Step 7 Damper airflows as required. Step 8 Repeat Steps 5 and 6 as required to confirm airflows 26 Air Flow Balancing using the Door Ports Models RNC155 and RNC200 Only The door ports ( MODELS RNC155 & RNC 200) are designed to quickly and measure the airflows for balancing. Normally the HRV would be balanced on high speed. If the HRV is connected to a forced air system, both systems should be set to run at the highest operational speed when balancing is performed. Balancing Procedure Step 1 Remove balancing port covers. Step 2 Insert one end of each connection hose into a rubber fitting. (Use light pressure until fitting is snug). Step 3 Attach the connection hoses to pressure gauge Step 4 Fresh Air - Connect hoses to door ports as illustrated (record reading). Step 5 Stale Air - Connect hoses to door ports as illustrated (record reading). Step 6 Refer to the Airflow Reference Chart for the conversion of gauge reading to airflow reading. Step 7 Damper the airflows as required to balance the system. The fresh airflow must equal the stale airflow. Step 8 Repeat steps 4 to 7 as required to confirm airflows.

Use this wiring configuration to prevent the Interface relay contacts from initializing the condenser unit. This problem can occur at the thermostat because the Y terminal is connected to the G terminal internal to the stat. When R and G are closed at the furnace (by dehumidistat or relay) 24 Volts is sent to G at thermostat. 24 Volts is then sent through Y which will initiate outdoor condenser.
