WIRING DIAGRAM
Dual Fuel Heating and Cooling Packaged System
NOTES:
1. Disconnect power before servicing.
208/230 Volt
5. For supply wire ampacities and overcurrent protection, see unit rating plate.
2. For supply connections use copper conductors only.
3. Not suitable on systems that exceed 150V to ground.
4. If any of the original wire as supplied with the furnace must be replaced, it must
be replaced with wiring material having a temperature rating of at least 105°C.
6. Ensure that wires from the blower remain connected to the board thermostat terminals after
making the field thermostat connections.
7. A heat pump thermostat with fossil fuel back-up heat capability is REQUIRED for this system.

DEFROST BOARD OPERATION:
-- Heat Pump operates in heating mode until the combination of outdoor ambient
and outdoor coil temperatures initiate a defrost cycle. The outdoor coil
temperature must be at or below 32˚F before the defrost cycle begins.
-- There must be a minimum of 20 minutes between defrost cycles. After this
time, temperature conditions must call for defrost continuously for 4 1/2
minutes before a defrost cycle is initiated.
-- The defrost cycle ends when either the outdoor coil temperature sensor reaches
the defrost terminate set point, or 13 minutes, 39 seconds of compressor run time
has elasped with the control in the defrost mode. (See installation instructions for
available terminate temperatures and their specific jumper location)
