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 house, program the temperatures to
be cooler (warmer) when the house is vacant or while occupants
are sleeping.
• During early morning hours, the need for cooling is usually minimal.
Look at the factory preprogrammed times and temperatures shown
on page 7. 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 temperatures,
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 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 on page 7 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.
