5. ELECTRICAL CONNECTION TO THE FURNACE
For a furnace connected to a cooling system:
On some older thermostats, energizing the “R” and “G” terminals at the furnace has the effect of energizing “Y” at the thermostat and
thereby turning on the cooling system. If you identify this type of thermostat, you must use the
ALTERNATE FURNACE INTERLOCK WIRING
.
STANDARD FURNACE INTERLOCK WIRING
ALTERNATE FURNACE INTERLOCK WIRING
WARNING
Never connect a 120-volt AC circuit to the terminals of the furnace interlock (standard wiring). Only use the low voltage class
2 circuit of the furnace blower control.
