1. With boilers, locate terminal on spark ignition module or gas valve (if standing pilot) which would normally be 24 volts
hot on a call for heat. With spark ignition systems, this terminal could be TH-W, 24 V, THS or T1 depending on the
spark ignition control.
2. With warm air furnaces, locate terminal W in furnace junction box.
3. Remove wire from this terminal and reroute to T1 on CK-92F.
4. With boilers, connect T3 on CK-92F to hot side of gas valve (if standing pilot) or to terminal TH-W, 24 V, THS or T1 if
spark ignition.
NOTE:
Remember, the correct terminal is the one that would normally be hot on a call for heat.
5. With warm air furnaces, connect T3 on CK-92F to terminal W in furnace junction box.
6. Connect T2 on CK-92F to a 24 volt neutral where convenient.
