Programming Thermostat Schedules — Before
programming the thermostat, plan the thermostat daily sched-
ule. 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 unoccupied time
period is active whenever an occupied time period is not
active. Fill in Table 1 below as an aid to programming the daily
schedules.
NOTE: When the sensor detects light (the space is occupied),
the thermostat will enter 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 ther-
mostat from entering Occupied 1 while the room is unoccu-
pied. If the Occupied 1 schedule is turned ON, the thermostat
will enter Occupied 1 per the schedule regardless of light acti-
vation. The Occupied 1 set points are used as the heating and
cooling set points during light activation. 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 sched-
ules, perform the following procedure:
1. Enter Programming mode by pressing the Program
button. The Occupied 1 annunciator will appear on the
thermostat 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 tem-
perature 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 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 continue. See
Fig. 5.
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 ARROW
and DOWN ARROW buttons to change the day of the
week until the desired starting day is shown. Possible
choices are M (Monday) through S (Sunday). Press the
Mode button when the desired day is shown.
