Follow the procedure below to configure the thermostat to match the installed
heating/cooling system, and customize feature operation as desired.
AC Power
The thermostat can be powered by 24
VAC power, or by batteries.
To wire the thermostat for AC power,
connect the common side of the cool-
ing transformer to the “C” terminal as
shown at left.

2-transformer systems only. (See wiring
diagram on page 5.)
Connect common
side of transformer
to “C” terminal
Install batteries in back of thermostat
(optional if AC powered).
Battery Power
The thermostat can be powered by
batteries alone or, if used with AC
power, can provide backup power.
During power interruptions the
batteries will save time/day settings
and power the display.
After installation, batteries can be
changed without removing the ther-
mostat from the wall (see page 15).
To Mount Thermostat
Align the 4 tabs on the wallplate with
corresponding slots on the back of the
thermostat, then push gently until the
thermostat snaps in place.
