12
If viewed as a single large screen, the layout is as follows:
The Month and Day entries select the month (1 to 12) and
day (1 to 31) of the holiday. The time settings are in 24-hour
time, with Start Time used to set the time of day to start of the
holiday. The End Time line is used to set the end of the holiday.
The NEXT item at the bottom of screen moves you to the next
holiday schedule set point.
Setting the month or day or start time and end time to 0 dis-
ables the holiday schedule.
The holiday schedule cancels any normal schedule set for
the holiday date and time. If a normal schedule is set from 0700
to 1800 hours and a holiday schedule is set for the same day
from 0800 to 1700, the unit will be unoccupied from midnight
to 0700. The unit will change to occupied mode at 0700 until
0800. At 0800 the holiday schedule forces the unit to
unoccupied mode until 1700. At 1700, control returns to the
normal schedule and the unit goes occupied from 1700 to
1800. At 1800, the unit returns to unoccupied mode per the
normal schedule.

to enter the CONFIGURATION menu.
2. Use the arrow keys to select OCCUPANCY, then press
<ENTER>.
3. Press the [OVERRIDE] softkey to adjust the override
schedules.
4. Use arrow keys to scroll around the screen and select the
data field to change. These buttons scroll through the data
fields, as well as up and down the screen.
5. To change a field, move the cursor brackets to the desired
field then press <ENTER>.
6. If the wrong field is entered or you do not want to change
a value, press [CANCEL] to leave the current setting in-
tact.
7. Press the [PREV] softkey to move the previous screen or
schedule. Press the [NEXT] softkey to move to the next
schedule screen.
If viewed as a single large screen, the layout is as follows:
The Month and Day entries select the month (1 to 12) and
day (1 to 31) of the override. The time settings are in 24-hour
time, with Start Time used to set the time of day to start of the
override. The End Time line is used to set the end of the over-
ride. The NEXT item at the bottom of screen moves you to the
next override schedule set point.
Setting the month or day or start time and end time to 0 dis-
ables the override schedule.
The override schedule has the highest priority of any sched-
ule. When an override schedule is active, it overrides any nor-
mal or holiday schedule and forces the unit to occupied mode.
In the example listed under the holiday schedule, assume an
override schedule is set for 1300 to 1400 of that day. The unit
operation remains the same, except the unit will switch to oc-
cupied mode from 1300 to 1400.
