Diagram #6C2: Forced Air Furnace having a Replacement Air Supply Duct together with an Exhaust Fan controlled by a designated Ventilation Switch and/or Bathroom Timer. Air Conditioner is not part of this system.

  1. Use Replacement Air Control Damper (Power Open) – (HAC-0x10-OPO)
  2. Ventilation Switch and/or Bathroom Timer to supply controlled 120Vac to Furnace area
  3. Relay Adaptor (ADP-1102-TWP) to function as a control center
  4. Relay Adaptor (ADP-0241-05A) to function as a fresh air supply when Thermostat is set to the cooling cycle

OPERATION:

  1. Replacement Damper opens to provide fresh air during the heating and/or cooling cycle.
  2. Ventilation Switch and/or bathroom timer turns on Ventilation Fan, opens Replacement Air Damper and turns on Furnace Fan simultaneously
  3. For the cooling cycle, (use when outside temperature cool) thermostat will simultaneously turn on the Furnace Fan and open the Replacement Air Damper
  4. Damper will remain closed during manual Furnace Fan operation
  5. On/Off Switch connected to (ADP-1102-TWP) Terminal #2 (as shown) allows manual control of the Replacement Air Damper to open as required

If installing an Air Conditioner at a later date, disconnect (ADP-0241-05A) from “Y” to leave Damper closed during A/C operation. For systems with existing A/C use Diagram #6C1 (to keep Damper closed during the A/C operation) or refer to Diagram #6C3 to open Damper during A/C operation.
