8. ONE DUAL BASEMENT HEAT PUMP PLUS ONE
GAS FURNACE
To configure one dual basement heat pump plus one
gas furnace, the STAGE Dip switch on AC power
module for Circuit 2 must be turned to ON. All other Dip
switches are OFF on both AC power modules. Two (2)
ambient sensors (one per AC power module), are
plugged into the proper connector (red) on each AC
power module. 115V AC (Circuit 1 and Circuit 2) are
connected properly to CIR 1 and CIR 2 terminal blocks;
12VDC, two thermostat wires from the furnace and
telephone cable communications line are properly
connected to Circuit 1 AC power module in the electri-
cal box.
NOTE: If a remote sensor(s) is used, it must be
plugged into the P4 (white) connector.
Improper connections can cause
component damage.
Typical installation for one com-
fort zone with dual basement heat
pump and one furnace. Comfort
control may serve as a room
temperature sensor, or a remote
sensor may be used.
