STEP 4. WIRE WALLPLATE TERMINALS

IMPORTANT
All wiring must comply with local codes and ordinances. If
unsure about household wiring procedures, call your local heat-
ing/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.
