Step 7. Wire Wallplate Terminals - Honeywell THE DIGITAL ROUND CT8775A Owner's Manual

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.
