running the factory preset program.

Now look at the factory preprogrammed times and temperatures shown below. If this program

will suit your needs, simply press PRGMRUN to begin

running the factory preset program.

If you want to change the preprogrammed times and temperatures, do the following.

Determine the time periods and heating and cooling temperatures for your weekday pro- gram. You must program 4 periods for each day (MOR, DAY, EVE, and NHT). However, you may use the same heating and cooling tempera- tures 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 MOR heating start time and temperature, and choose 7:00 AM and 76° as the weekday MOR cooling start time and temperature).

Use the following table 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.
