STEP 7. 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.
IMPORTANT
Remove the factory-installed jumper connecting terminals R
and Rc on the CT8775C Thermostat if wires will be con-
nected to both of these terminals.
❑
For wiring diagrams, see pp 16-17.
❑
Loosen the terminal screws. Slip each wire beneath its matching
terminal. Wraparound and straight connections are both acceptable,
(see illustration). Tighten the terminals.
❑
Plug the hole in the wall with insulation to help prevent drafts from
adversely affecting thermostat operation.
