Step 7. Connect Wires to New Wallplate
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
