15 The word BATTERY will be displayed con- tinuously (non-flashing) when 24 VAC power is not being supplied to the thermostat and the thermostat is operating on battery power only. • AUDIO PROMPTING — Each time you press a button, the thermostat will beep. • BACKLIT DISPLAY — When you press any button on the thermostat, the display is lit f[...]

16 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 [...]

These will be your Period 3 temperature settings. 4a. What time does the building become vacant? b. What temperature should the building be at this time? These will be your Period 4 temp[...]

18 However, you may use the same heating and cooling temperatures for consecutive time periods. Also keep in mind that, for any given day, you can only program one set of times for both heating and cooling (for ex- ample, if you select 5:00 AM to begin heat- ing period 1 on Monday, then your cooling period 1 for Monday will also begin at 5:00 AM).
