STEP 4. WIRE WALLPLATE TERMINALS

IMPORTANT

All wiring must comply with local codes and ordinances. If unsure about household wiring procedures, call your local heating/air-conditioning contractor.

Refer to the labels you placed on the wires when you removed the old thermostat (see illustration).

❑Match the letter of your old thermostat wire with the corresponding terminal letter on your new thermostat. Refer to Table 2.

❑Remove the factory-installed jumper connecting terminals R and RC if wires are connected to both of those terminals.

❑For wiring diagrams, if needed, see pp 21-22.

❑Loosen the terminal screws. Slip each wire beneath its matching terminal. Wraparound and straight connections are both acceptable, (see illustration). Tighten the terminals.
