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 fac-
tory preset program.
If you want to change the preprogrammed times and tempera-
tures, follow these steps.
Determine the time periods and temperatures for your daily
programs. You must program four periods for both the weekday
and weekend program. However, you may use the same heat-
ing and cooling temperatures for consecutive time periods.
You can choose start times, heating temperatures, and cool-
ing temperatures independently for each day programs (for
example, 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.
