*FURNACE INTERLOCK RELAY, PART # 12658

VE0009A

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.
