Electrical Connections
Make wiring connections to the unit as indicated on enclosed wiring diagram. As with all gas appliances using electrical power, this furnace shall
be connected into a permanently live electric circuit. It is recommended that furnace be provided with a separate "circuit protection device"
electric circuit. The furnace must be electrically grounded in accordance with local codes or in the absence of local codes with the National
Electrical Code, ANSI/NFPA 70 or CSA C22.1 Electrical Code, if an external electrical source is utilized. The integrated furnace control is
polarity sensitive. The hot leg of the 120V power supply must be connected to the black power lead as indicated on the wiring diagram.
Refer to the Wiring Diagram section in this document and unit wiring diagram attached to furnace.

FIELD WIRING DIAGRAM FOR S9V2-VS WITH ONE / TWO STAGE AC OR HEAT PUMP
NOTES:
1) HP = Wiring used for Heat Pump System.
2)
CS
= wiring
used
for
Conden
sate Switch (2 Op!ons).
3)
Y1 and/or
Y2
must
be
connected from the thermostat to
the IFC for proper airflow.
4) Remove Y1-O jumper for HP systems. O terminal must be
connected as shown for gas hea!ng opera!on during
defrost.
5) If the thermostat does not have a W2, or there are not
enough conductors, jumper W1 to W2 at the IFC.
6) A/TCONT824 thermostats do not require the use of X2.
7) For PWM (BK) enabled thermostats, cut the BK jumper on
the IFC and connect wiring.
