OPERATION
Before you begin using 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 fea-
tures of the thermostat.
• SIMULTANEOUS HEATING/COOLING STORAGE — You
can enter both your heating and cooling setpoints at the
same time. There is no need to reset the thermostat at the
beginning of each season.
• LOW BATTERY INDICATOR — If the 3 “AA” alkaline
batteries are low and should be replaced, the display will be
blank except for the word BATTERY. 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 the word BATTERY. When the duration
of a low battery condition exceeds four weeks, the setpoint
is altered by 10 degrees to signal that the batteries must be
replaced.
• °F/°C CONVERTIBILITY— After ten seconds of no key
activity, when the thermostat is in the temperature display
adjustment mode, or 30 seconds after power up, pressing
and at the same time will switch the LCD temperature
display between Fahrenheit and Celsius.
• TEMPERATURE DISPLAY ADJUSTMENT — Your new
thermostat has been accurately set in our factory. However,
if you wish, you may adjust your new thermostat tempera-
ture display to match your old thermostat. This can be
accomplished (within a ±4° range) as follows:
1. Press and at the same time within 30 seconds of
applying power.
2. Press or to adjust the displayed temperature to
your desired setting.
3. After setting your desired temperature, do not press any
buttons for ten seconds. The thermostat will continue
operating at the changed temperature setting.
SETTING THE THERMOSTAT
This thermostat is very easy to operate. Set the SYSTEM button
to either HEAT or COOL, then press or until the tempera-
ture you want to maintain is shown on the right side of the
display. If you want to turn the system off, just move the
SYSTEM switch to OFF.
The FAN switch controls the fan operation. When the FAN
switch is set to AUTO, the fan will cycle with the furnace or air
conditioner. When the FAN switch is set to ON, the fan will run
continuously, regardless of SYSTEM switch position.
