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 body and the base. To remove the body, gently pull it
straight out from the base. To replace the body, line up the body with
the base and press gently until the body 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.
• SIMULTANEOUS HEATING/COOLING PROGRAM STOR-
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 temperature
at the selected temperature until the next program period begins.
Then the thermostat will automatically revert to the program.
• HOLD TEMPERATURE — The thermostat can hold any tempera-
ture within its range for an indefinite period, without reverting to
the programmed temperature. Press HOLD button. “HOLD” will
be displayed. Then choose the desired temperature by pressing
or . The thermostat will hold the room temperature
at the selected setting until you press the RUN button to start
program operation again.
• ENERGY MANAGEMENT RECOVERY — Energy Management
Recovery (EMR) causes the thermostat to start heating or cool-
ing early to make the building temperature reach the program
setpoint at the time you specify. Heating will start 5 minutes early
for every 1° of temperature required to reach setpoint. Cooling
will start approximately 15 minutes early for every 1° because
it takes longer to reach temperature. Clipping W903 jumper will
disable EMR.
Example: You select EMR and have your heating programmed
to 65° at night and 70° at 7 AM. If the building temperature is 65°
the difference between 65° and 70° is 5°. Allowing 5 minutes per
degree the thermostat setpoint will change to 70° at 6:35 AM.
• °F/°C CONVERTIBILITY — The factory default setting is Fahr-
enheit. Clipping W904 jumper on the circuit board (see fig. 1)
will alter this feature to Celsius temperature setting.
• LOW BATTERY INDICATOR — If the 2 “AAA” alkaline bat-
teries are low and should be replaced, the display will be
blank except for
. When the batteries are low, pressing
any button will cause the display to operate for ten seconds.
After ten seconds, the display will return to blank except for
. After has been displayed for 4 weeks, the
thermostat will raise the temperature 10 degrees above your
setpoint in COOL mode and will drop temperature 10 degrees
below your setpoint in HEAT mode. You cannot program with low
batteries, but you can override setpoint temperature.
• TEMPERATURE DISPLAY ADJUSTMENT — Your new ther-
mostat has been accurately set in our factory. However, if you
wish, you may adjust your new thermostat temperature display
to match your old thermostat. This can be accomplished (within
a ±3° range) as follows:
