1. Use Replacement Air Control Damper (Power Open) - (HAC-0x10-OPO). 
2. Relay Adaptor (ADP-0241-05A) to function as a fresh air supply when thermostat is set to the cooling or heating cycle.
 
OPERATION:  
1. Thermostat will simultaneously turn on the Furnace Fan and open the Replacement Air Damper to provide fresh air during the heating and/or cooling  cycles.  
2. Damper will remain closed during manual furnace fan operation.
3. To override the normally closed damper, use an optional SPDT Toggle Switch as shown. For ease of installation, consider a Hoyme ready mounted optional switch (ADP-0240-3WS) in place of SPDT toggle switch. (See Diagram #4A2)
