Look at the factory preprogrammed times and temperatures
shown below. If this program will suit your needs, simply press the
RUN PRGM 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 heating and cooling tempera-
tures for your weekday and weekend programs. You must
program four periods for both the weekday and weekend pro-
gram. 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 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.
