Programming Thermostat Schedules —
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.
NOTE: When the sensor detects light (the space is occu-
pied), 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 thermostat from entering Occupied 1 while the room is
unoccupied. If the Occupied 1 schedule is turned ON, the
thermostat will enter 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 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 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
