temperature is shown. The range of acceptable values is 35 to 99 F (1 to 37 C). Press the Mode button to con- tinue. See Fig. 5.

3.The heating set point for Occupied 1 will be displayed. Use the UP ARROW and DOWN ARROW buttons to raise or lower the heating set point until the desired tem- perature is shown. The range of acceptable values is 35 to 99 F (1 to 37 C). Press the Mode button to con- tinue. See Fig. 5.

Programming Thermostat Schedules Ð Be- fore programming the thermostat, plan the thermostat daily schedule. The schedule is divided into 7 days (Monday through Sunday). Each day can have 2 (Occupied 1, Unoccupied), 3 (Occupied 1, Occupied 2, Unoccupied), or 4 (Occupied 1, Occupied 2, Occupied 3, Unoccupied) time periods. Each occupied time period has a start time, stop time, heating set point and a cooling set point. The unoccupied time period has a heating set point and a cooling set point. The unoc- cupied time period is active whenever an occupied time period is not active. Fill in Table 1 below as an aid to pro- gramming the daily schedules.

PROGRAMMING MODE Ð To program the daily sched- ules, perform the following procedure:

1.Enter programming mode by pressing the Program but- ton. The Occupied 1 annunciator will appear on the ther- mostat display. See Fig. 5. Use the UP ARROW and DOWN ARROW buttons to set the maximum number of Occupied periods available. The thermostat can be set to 1, 2, or 3. After the number of Occupied periods has been selected, press the Mode button.

2.The cooling set point for Occupied 1 will be displayed. Use the UP ARROW and DOWN ARROW buttons to raise or lower the cooling set point until the desired

4.The cooling set point for Unoccupied will be displayed. Use the UP ARROW and DOWN ARROW buttons to raise or lower the cooling set point until the desired tem- perature is shown. The range of acceptable values is 35 to 99 F (1 to 37 C) or ``OF''(no unoccupied cooling). Press the Mode button to continue.

5.The heating set point for Unoccupied will be displayed. Use the UP ARROW and DOWN ARROW buttons to raise or lower the heating set point until the desired tem- perature is shown. The range of acceptable values is 35 to 99 F (1 to 37 C) or ``OF'' (no unoccupied heating). Press the Mode button to continue.

6.The day of the week will be shown. Use the UP AR- ROW and DOWN ARROW buttons to change the day of the week until the desired starting day is shown. Pos- sible choices are M (Monday) through S (Sunday). Press the Mode button when the desired day is shown.

7.The Start Time for Occupied 1 will be displayed. Use the UP ARROW and DOWN ARROW buttons to raise or lower the time until the desired Start Time is shown. Press the Mode button to continue. See Fig. 6.
