SCHEMATIC WIRE DIAGRAM OF
ADAPTOR ADP- 0241-10A
Note: This marking is also on the cover of the
Adaptor unit as well as on a label to be placed
next to the wiring diagram of the appliance.
This Adaptor uses a 24Vac Coil SPDT to
develop a 10A capacity for 120Vac if needed
and a 24Vac Coil DPDT to develop multiple
contact points for 24Vac. Coils are connected
in parallel and therefore act as one relay.
Schematic Wire Diagram ADP-0241-10A
Activated by a Manual or Automatic Switch
to Control a Furnace Fan a 120Vac i.e.
Booster Fan and a Fresh Air Inlet Damper.
Damper remains closed during furnace firing.

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
#6
(G

is then to be
connected to ‘G’ of the furnace and Thermostat
wire ‘G’ is to be connected to

of the
Adaptor.
