PROGRAMMING YOUR THERMOSTAT
This section will help you plan your thermostat’s program to
meet your needs. For maximum comfort and effi ciency, keep
the following guidelines in mind when planning your program.
• When heating (cooling) your building, program the
temperatures 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/HOLD button to begin running
the factory preset program.
PROGRAMMING
If you want to change the preprogrammed times and
temperatures, follow these steps.
Determine the time periods and temperatures for your program.
You must program four periods for each day. 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
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 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.
