STEP 4. 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 old thermostat wire with the corresponding
terminal letter on new thermostat. Refer to Table 1.
❑ Remove factory-installed jumper connecting terminals R and
RC if wires are connected to both of those terminals.
❑ For wiring diagrams, if needed, see Wiring Diagrams section.
❑ Loosen terminal screws. Slip each wire beneath matching
terminal. Wraparound and straight connections are both
acceptable, (see illustration). Tighten terminals.
❑ Plug the hole in the wall with insulation to help prevent
drafts from adversely affecting thermostat operation.
