Never connect a 120 volt AC circuit to the terminals of the furnace

interlock (Standard Wiring). 

Only use the low voltage class 2 circuit.

!

!

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 Interlock Wiring”. 

For a furnace connected to a cooling system:
