The screens will step through the Start Time and then the Stop Time
for each day of the week. You can quit at any point in the process by
pressing
<ESC> . There are two Start/Stop events available per day, so
the screen will show which event is being programmed. If you need
only one event, keep Event #2’s times set at ZERO.
All times are in 24-hour military format, so 5:00 PM would be entered
as 1700.
If both the Start and Stop Times are ZERO, the schedule is in a continu-
ous OFF mode. (Also, use for Remote Forced Occupied applications
using the Forced Occupied Binary Input.)
If both the Start and Stop Times are 2359, the schedule is in a continu-
ous ON mode.
NOTE: The second line displays which day of the week is cur-
rently being programmed. The day of the week automati-
cally increments as you exit the Event #2 screen for the
day and continue to the next day’s Event #1 screen.
CAUTION: The controller ships with all schedules set to
zero so that the controller will not attempt to heat
or cool before you have confi gured the system.

The screens will step through the 14 possible holidays, one period at
a time. Line 2 shows which holiday is currently being programmed.
Since a holiday period can encompass more than one day, you need to
program the day the holiday starts and the day the holiday ends. If your
holiday only lasts one day, simply set both the Start Day and the Stop
Day to the same value. Remember to combine the month and day into
a single four-digit value.
EXAMPLE:
704 = July 4 th (NOTE: Leading zero not required)
1225 = December 25 th

If you are using the internal scheduling capability of the Unit Control-
ler, set the schedule hours and holiday periods from the menu shown
above. You can also force the unit to operate continuously in occupied
or unoccupied mode by selecting the Schedule Override menu item and
entering the desired command.
If you are using an external contact closure to signal the occupied mode,
you must access the Week Schedule Screens and set all start and stop
times to zero to prevent the internal schedule from turning the equip-
ment on when you don’t want it to operate.
