PROGRAMMING YOUR THERMOSTAT Now you are ready to program your thermostat. 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. • When heating (cooling) your building, pro- gram the temperatures to be cooler (warmer) when the building is vacant or during peri- ods of low activity. - Page 20 2a. What time do the building occupants reach a maximum activity level (using lights, equip- ment, meeting rooms, etc.)? b. What temperature should the building be at this time? These will be your DAY tempera- ture settings. 3a. What time do the building occupants reach a minimum activity level (limited personnel in building)? b.
- Page 21 b. What temperature should the house be at this time? These will be your NHT (night) temperature settings. Now look at the factory preprogrammed times and temperatures shown on the following page. If this program will suit your needs, simply press to begin running the factory preset pro- PRGM gram.
