OPERATING YOUR THERMOSTAT
Before you begin programming your thermo-
stat, you should be familiar with its features and
with the display and the location and operation
of the thermostat buttons. The information in
this section will help you become familiar with
your new thermostat so that you can easily
program it.
Your thermostat consists of two parts: the ther-
mostat body and the subbase.
Remove power from the system at the
circuit breaker/fuse box before remov-
ing or attaching the thermostat body.
Equipment damage and/or personal in-
jury could occur.
The subbase is attached to the wall, but you can
remove the thermostat body for easy program-
ming. To remove the thermostat body from the
subbase, grasp the thermostat body and gently
pull it straight out from the subbase. To attach
the thermostat body, line up the two terminal
pins on the lower section of the thermostat back
with the matching connector on the subbase.
Insert these, then gently pivot the thermostat
body up to connect the six pin connectors on the
upper portion of the thermostat back. Gently
push until the snap connectors engage. DO
NOT FORCE OR PRY THE THERMOSTAT, as
this may damage the unit.
