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.

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.
