Alternate furnace interlock wiring
For a furnace connected to 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”. An additional control relay will then have to be installed.
WARNING
010
!
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.
