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 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.
Planning Your Program
Look at the factory preprogrammed times and temperatures
shown in the sample schedule. 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 week-
day and weekend programs. You must program four periods
for each day 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 each day programs (for ex-
ample, you may select 5:00 AM and 70° as the Monday 1st
period heating start time and temperature, and also choose
7:00 AM and 76° as the Monday 1st period cooling start time
and temperature).
Use the following table to plan your program time periods and
the temperatures you want during each period. Fill in the
complete table to have a record of your programs.
