The C (common wire) terminal does not have to be
connected when the thermostat is powered by batteries.

NOTE: In systems with no emergency heat relay a jumper
can be installed between E and W2 to turn thermostat into
a single stage control.

Terminal designations

This thermostat is shipped from the factory to operate a conventional heating and cooling system. See the "heat pump"

Instructions

Attaching the thermostat to the subbase

Align the 4 tabs on the subbase with corresponding slots
on the back of the thermostat, then push gently until the
thermostat snaps in place.

Battery installation

Battery installation is recommended even if thermostat
is hardwired (C terminal connected). When thermostat
is hardwired and batteries are installed, the thermostat
will activate a compressor delay of 5 minutes when the
thermostat detects a power outage from the hardwired
power supply (batteries included).

On the back of the thermostat
insert 2 AA alkaline batteries
(included).

Important:

The low battery indicator is displayed when the AA battery power is low. If the user fails to replace the battery
within 21 days, the thermostat display will only show the low battery indicator as a nal warning before the thermostat
becomes inoperable. For more information, see Battery installation and replacement above.

Important:

The low battery indicator is displayed when the AA

battery power is low. If the user fails to replace the
battery within 21 days, the screen will only show the low
battery indicator but maintain all functionality. If the user
fails to replace the batteries after an additional 21 days
(days 22-42 since rst “low battery” display) the set points
will change to 55°F (Heating) and 85°F (Cooling). If the
user adjusts these setpoints away from these it will hold
for 4 hours then return to either 55°F or 85°F. After day
42 the batteries must be replaced immediately to avoid
freezing or overheating because the thermostat will shut
the unit off until the battery is changed.

Programming

All our programmable thermostats are shipped with an
energy saving pre-program. You can customize this
default program by following the Set Program Schedule.

Your thermostat can be programmed to have each day of
the week programmed uniquely (7 days), all the weekdays
the same, a separate program for Saturday, and a separate
program for Sunday (5+1+1), or non-programmable.
