5. ELECTRICAL CONNECTION TO THE FURNACE

0 ! 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.

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.
