Heating/Cooling Schedule Plan
* We suggest that you program the thermostat so that the heating/cooling system
has about 30 minutes to reach the desired temperature (for example, if the first
person gets up at 6:00 AM, program the first period to begin at 5:30 AM).

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
STORAGE — 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 automati-
cally revert to the program.
• HOLD TEMPERATURE — The thermostat can hold any
temperature within its range for an indefinite period, without
reverting to the programmed temperature. Press HOLD
TEMP 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 PRGM button to start program
operation again.
• °F/°C CONVERTIBILITY — Press and hold SET TIME and
HOLD TEMP buttons until the temperature display is in
Celsius (°C). To display Fahrenheit (°F), repeat the pro-
cess.
• 12-HOUR/24-HOUR CLOCK DISPLAY — The clock is set
to display 12-hour time, which means that the clock will
display AM and PM time (12:00 AM is midnight; 12:00 PM is
noon). However, you may want to display a 24-hour clock
(military-style time). The 24-hour clock display will show 1:00
PM as 13:00, 2:00 PM as 14:00, and so on. To change to the
24-hour clock display, press and hold SET TIME and RUN
PRGM buttons at the same time. In the 24-hour clock mode,
AM and PM are not displayed.
• 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. You cannot program with low
batteries, but you can override setpoint temperature.
• 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 VIEW PRGM and HOLD TEMP buttons at the
same time.
2. Press or to adjust the displayed temperature to
your desired setting.
3. Press RUN PRGM to resume normal program operation.
PROGRAMMING YOUR THERMOSTAT
Now you are ready to program your thermostat. This section will
help you plan your thermostat’s program to meet your needs.
For maximum comfort and efficiency, keep the following guide-
lines in mind when planning your program.
• When heating (cooling) your building, program the tem-
peratures to be cooler (warmer) when the building is vacant
or during periods of low activity.
• During early morning hours, the need for cooling is usually
minimal.
Look at the factory preprogrammed times and temperatures
shown below. If this program will suit your needs, simply press the
RUN PRGM button to begin running the factory preset program.
If you want to change the preprogrammed times and tempera-
tures, follow these steps.
Determine the time periods and heating and cooling tempera-
tures for your weekday and weekend programs. You must
program four periods for both the weekday and weekend pro-
gram. However, you may use the same heating and cooling
temperatures for consecutive time periods. You can choose
start times, heating temperatures, and cooling temperatures
independently for both weekday and weekend programs (for
example, you may select 5:00 AM and 70° as the weekday 1st
period heating start time and temperature, and also choose
7:00 AM and 76° as the weekday 1st period cooling start time
and temperature). Use the table at the bottom of the page to plan
