If NO was selected, the schedule will automatically change
to the next day and the user must enter the occupied and
unoccupied schedules for that day.
NOTE: Occupied 1 schedule heating and cooling set points
are the same for each day. Occupied 2 and 3 set points
may be set to different values for each day of the week.
If YES was selected, the schedule will be copied to the
next day. The schedule copy may be repeated until Sun-
day is reached. The Sunday schedule cannot be copied
to Monday.

entered, press the Program button to exit programming

If only one occupied schedule is selected, the Occupied 2
and 3 schedules are skipped. If the start time is set later in
the day than the stop time, the program will run from mid-
night of that day to the stop time and then from the start time
to midnight. If the same start and stop times are pro-
grammed for an occupancy schedule, the thermostat will be
in Occupied mode for 24 hours. If one occupied period starts
or stops within another occupied period, the lower num-
bered schedule has priority. For example, if schedule Oc-
cupied 3 is running for 24 hours and Occupied 2 schedule
comes on from 1 to 3 PM, the set points from Occupied 2
are in effect from 1 to 3 PM.
OVERRIDING THE SCHEDULE — The schedule can be
overridden by pressing the UP or DOWN ARROW buttons
to change the desired temperature. The thermostat will use
the new set point until the next scheduled time period starts.
