Before you begin programming your thermostat, you should be
familiar with its features and with the display and the location and
operation of the thermostat buttons. Your thermostat consists of
two parts: the thermostat cover and the base. To remove the
cover, gently pull it straight out from the base. To replace the
cover, line up the cover with the base and press gently until the
cover snaps onto the base.

OPERATING FEATURES
Now that you are familiar with the thermostat buttons and display,
read the following information to learn about the many features of
the thermostat.

AGE—When programming, you can enter both your heating
and cooling programs at the same time. There is no need to
reprogram the thermostat at the beginning of each season.
• TEMPERATURE OVERRIDE—Press or until the
display shows the temperature you want. The thermostat will
override current programming and keep the room tempera-

begins. Then the thermostat will automatically revert to the
program.

• HOLD TEMPERATURE—The thermostat can hold any tem-
perature within its range for an indefinate period, without
reverting to the programmed temperature. Press HOLD
button. HOLD will be displayed. Then choose the desired
hold temperature by pressing
or . The thermostat
will hold the room temperature at the selected setting until
you press RUN button to start program operation again.
• LOW BATTERY INDICATOR—If the 2 “AAA” alkaline batter-
ies are low and should be replaced, the display will be blank
except for “LO BATT”. When the batteries are low, pressing
any button will cause the display to operate for ten seconds.
After ten seconds, the display will be blank except for “LO
BATT”. You cannot program with low batteries, but you can
override setpoint temperature. When “LO BATT” occurs, the
thermostat will raise the temperature 10 degrees above your
setpoint on “COOL” mode and will drop temperature 10
degrees below your setpoint on “HEAT” mode.
• SIMPLIFIED COPY DAY FUNCTION—This feature allows
Monday’s program to be copied into the rest of the week’s
programming. This feature is only available the first time
you program your thermostat. To use this feature, simply
enter the program for Monday as described in PROGRAM-
MING YOUR THERMOSTAT, and then press RUN, or HOLD.
