Note:
For PC damper only, a toggle switch in
series with 24Vac electrical supply line to the
Damper will cause it to open as required.
* Note:
For
PC damper without relay
and if
adding a Combustion Air Damper, re-connect
Fresh Air Damper from furnace ‘C’ to Green
wire of the Combustion Air Damper. Both
dampers will open during firing of the furnace.
* Note:
If existing ventilation relay (auxiliary
relay switch) cannot be located, relay wires
presently connected to ‘R’ and ‘G’ of the
furnace are to be re-connected to ‘3’ of ADP
and ‘C’ of the furnace. ADP ‘WHT’ will then
go to ‘G
F
’ of the furnace and ADP ‘RED’ will
go to ‘G
T
’ of the thermostat (if used).
