PROGRAMMING YOUR THERMOSTAT

This section will help you plan your thermostat’s program to meet
your needs. For maximum comfort and efficiency, keep the
following guidelines in mind when planning your program.

• When heating (cooling) your building, program the tempera-

tures 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
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 temperatures for your weekday
and weekend programs. You must program four periods for both
the weekday and weekend program. 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 week-
end 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 your program time periods and the temperatures you
want during each period. You may also want to look at the sample
program table to get an idea of how the thermostat can be
programmed.
