release tab on the bottom of the thermostat. (See Figure 2.)
Position wallplate on wall and pull existing wires through
large opening. Then level for appearance. Mark holes for plas-
tic anchors provided if your existing holes do not line up with
those on the Climate Technology wallplate.
Drill holes with 3/16" bit and gently tap anchors into the
holes until flush with wall.
Reposition wallplate to wall, pulling wires through large

Connect Wires and Mount Thermostat Cover to Wallplate
Straighten bare end of each wire and cut or strip it to 1/4”
maximum. Insert each labeled wire into the bottom of the
maching terminal. Refer to figures 4 and 5.
Hold the wires in each terminal and tighten the terminal
screws securely, otherwise a loose wire could cause opera-
tional problems with your system or thermostat.
Push excess wire back into hole to prevent interference with
mounting of the thermostat.
Make sure the Power Switch is set to OFF.
Insert two AAA size alkaline batteries, observing the polarity
marked on the unit.
Insert the upper tabs on the thermostat body into the slot at
the top of the wallplate. Press bottom of the thermostat body
to snap it into the wallplate. (NOTE:
Do not force the ther-
mostat onto the wallplate, as the terminal pins may be
damaged. If it does not snap properly, the thermostat
may not work.
)
Switch on the main power at the panel or furnace.
