1. Match the labeled wires to the letter designations on the 

wallplate.

2. Select the correct letter designations to follow for your system. 

If you have a standard heating and/or cooling system, use the 

CONVENTIONAL letter designations. If you have a heat pump 

system, use the HEAT PUMP letter designations to wire the 

new thermostat.

3. If wires are to be connected to both Rc and R, loosen the Rc 

and R screw terminals and remove the metal jumper wire.

4. If only one of the terminals, Rc or R, is to be connected, leave 

the metal jumper wire in place.

See table on page 29 to help you determine if you have a 

CONVENTIONAL or HEAT PUMP system.
