17 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.
