8.1.1 SCHEDULE SCREEN
When programming the 'SCHEDULE SCREEN' the
Select button is used to enable the cursor arrows which
are used to highlight the day and the start or stop times
that are to be modified. The ' ✓ ' (Check) key is used to
program the Start / Stop times for that day.
For the Start / Stop schedule to function correctly
each start time must have a corresponding stop
time which occurs later in that day.
The programmed schedule for a given day can be
cancelled by setting both the Start time and Stop
time to 12:00AM.
If the start time equals the stop time (with any time
other than 12:00AM), the unit is OFF for that day.
If the unit is to operate continuously through
several days, the stop time of Day 1 can be set to
11:59PM and the start time of Day 2can be set to
12:00AM. The unit will not stop but continue to
operate until the stop of Day 2.
A standard set of start / stop times can be defined
which are utilised every week. Exception Start /
Stop combinations for any day of the week up to 6
weeks in advance are then specified. At the end of
each week the schedule for the next week is
created by combining the standard week definition
and the next defined exception week. The
schedule is then updated as each of the exception
weeks "shifts down", leaving a new, blank
exception week in the 6th week slot.
