such as plaster or wood, drill 7/32-in. holes. Gently tap
provided anchors into the drilled holes until flush with
the wall.
❑ Reposition the wallplate, pulling wires through the
wiring opening. Loosely insert the mounting screws
into the holes.

procedures, call your local heating and air conditioning
contractor.

❑ Plug the hole in the wall with insulation to help prevent
drafts from adversely affecting thermostat operation.
Refer to the labels you placed on wires when you
removed your old thermostat.
The CT3451 Thermostat is powered with 3AA alkaline
batteries and is adaptable to most 18 to 30 Vac heating-
cooling systems. Refer to Fig. 6 through 10 for typical
system wiring diagrams.
❑ Match the letter of your old thermostat wire with the
terminal of the corresponding letter on your new
thermostat. Refer to Fig. 4.
