Color Wiring Diagram #4a

Diagram #4A: Forced Air Furnace having a replacement air supply duct.

ADDED: Power Open Replacement Air Control Damper (HAC-0x10- OPO).
 
OPERATION:  
1. Replacement air damper is interconnected to the furnace so that the damper opens to provide fresh air during the heating cycle and closes to conserve energy when the fire stops. Adjustment of the Heat Anticipator is required on a regular type thermostat. 
2. See Diagram #4A1 for installing a SPDT Toggle Switch that is designed to hold the Damper continually open. 
 
N.B. Replacement Air Damper is not affected by the ‘Manual’ setting of the furnace fan.
