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).
qMatch the letter of your old thermostat wire with the corresponding
terminal letter on your new thermostat. Refer to Table 1.
qFor wiring diagrams, if needed, see page 21.
qLoosen the terminal screws. Slip each wire beneath its matching
terminal. Wraparound and straight connections are both acceptable,
(see illustration). Tighten the terminals.
qPlug the hole in the wall with insulation to help prevent drafts from adversely affecting thermostat operation.
qMatch the terminals from your old thermostat to the terminals on the CT3611. Find the column from Table 1 that
matches your existing thermostat wire terminals to help you match the terminals correctly.
