11. The Copy command can be used to copy the previous
day's schedule if the schedules are the same. The copy
command becomes available after all the occupied pe-
riods are programmed in a day. Use the UP ARROW to
change the copy command to YES. Use the DOWN AR-
ROW to change the copy command to NO. Press the
Mode button when the choice has been made. See
Fig. 7.
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.
12. After all the times and set points for each day have been
entered, press the Program button to finish entering the
schedule.
NOTE: The thermostat will continue to follow the schedule
until a new one is entered.
• 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 midnight of that day to the stop
time and then from the start time to midnight.
• If the same start and stop times are programmed for an
occupancy schedule, the thermostat will be in Occupied
mode for 24 hours.
• If one occupied period starts or stops within another oc-
cupied period, the lower numbered schedule has priority.
For example, if schedule Occupied 3 is running for 24 hours
and occupied schedule 2 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 during operation by pressing the UP or DOWN
ARROW buttons to change the desired temperature. The ther-
mostat will use the new set point until the next scheduled
time period starts.
