has a start time, stop time, heating set point, and cooling set point. The un-
occupied time period has a heating set point and a cooling set point. The
unoccupied time period is active whenever an occupied time period is not
active. Fill in Table 1 on page 12 as an aid to programming the daily
schedules.
NOTE: When the sensor detects light (the space is occupied), the thermostat
will enter into Occupied 1 mode. If the room is dark, the thermostat will
follow its programmed schedule. The Occupied 1 schedule should be turned
OFF to keep the thermostat from entering Occupied 1 while the room is un-
occupied. If the Occupied 1 schedule is turned ON, the thermostat will enter
into Occupied 1 per the schedule regardless of light activation. The Occupied
1 set points are used as the heating and cooling set points during light ac-
tivation. The Unoccupied set points should be used as non-work hour set
points (before 8:00 AM and after 5:00 PM) when using light activation. For
times when the building is unoccupied during work hours (Monday through
Friday, 8:00 AM to 5:00 PM), the Occupied 2 schedule should be turned ON,
and can be used for moderate energy savings with set points of 80 F for
cooling and 65 F for heating.
PROGRAMMING MODE — To program the daily schedules, perform the
following procedure:
1. Enter programming mode by pressing the Program button. The Occu-
pied 1 annunciator will appear on the thermostat display. See Fig. 5. Use
the UP ARROW and DOWN ARROW buttons to set the maximum num-
ber 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 AR-
ROW and DOWN ARROW buttons to raise or lower the cooling set
point until the desired temperature is shown. The range of acceptable
values is 35 to 99 F (1 to 37 C). Press the Mode button to continue. See
Fig. 5.
3. The heating set point for Occupied 1 will be displayed. Use the UP AR-
ROW and DOWN ARROW buttons to raise or lower the heating set point
until the desired temperature is shown. The range of acceptable values
is 35 to 99 F (1 to 37 C). Press the Mode button to continue. See Fig. 5.
