Programming Your Thermostat

Entering Your Program

This section will help you plan your thermostat’s program to meet your needs. For maximum comfort and efficiency, keep the following guidelines in mind when planning your program.

Follow these steps to enter the heating and cooling programs you have selected.

•When heating (cooling) your building, program the tem- peratures 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 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 temperatures for your week- day and weekend programs. You must program four periods for each day 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 each day programs (for ex- ample, 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.
