Week Schedules
From the Unit Schedule Menu, select Week Schedules. The following
two screens will appear in order:
Event #1
Schd
Sunday Event #1
Start Time..: XXXX
Stop Time...: XXXX
Event #2
Schd
Sunday Event #2
Start Time..: XXXX
Stop Time...: XXXX
If you are using the internal scheduling capability of the Controller, set
the schedule hours and holiday periods from the menu shown above.
You can also force the unit to operate continuously in occupied or unoc-
cupied 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 equipment
on when you don’t want it to operate.
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. (Use for Remote Signal Contact.)
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
currently being programmed. The day of the week
automatically 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.
