About start and stop times
Here are some general rules about setting start and stop times:
• It is only necessary to program start and stop times for schedules that are activated
automatically.
• The time may be entered in either 12 or 24-hour format. If the display is in English, and the
hour entered is less than 13, the display prompts you to specify
AM or PM .
• If you assign identical start and stop times for a schedule, for example, 04:00 start and 04:00
stop, the schedule is in effect all day. The only exception to this is a start and stop time of
00:00; in this case the schedule is off for the day.
• You may assign overlapping times. For example, if schedule 1 is assigned from 9:00 a.m. to
4:00 p.m. and schedule 2 is assigned from 1:00 p.m. to 5:00 p.m., then the start time of the
second schedule is treated as a stop time for the first schedule.
This is also true if two schedules have the same start time but different stop times. The stop
time of the shorter schedule is treated as the start time of the longer schedule.
• If one schedule starts and stops within the times of another schedule, the first service
temporarily ends when the second service starts. The first service then resumes when the
second service has ended.
• Some schedules start and stop at the same times each day: use COPY to copy the start and
stop times from one day to the next.
Warning:
Start and stop times do not span days.
When you program a schedule to start in the evening and stop in the morning, it does not carry
over into the next day. For example, if you program Night service for Friday (22:00 to 6:00), the
system turns on Night service from midnight to 6 am on Friday, and then again from 10 p.m. to
midnight on Friday, as shown in the diagram below.
