Time Windows

A time window is a period of time during which an event is permitted,
or a specific time used to trigger an event. Note that time windows are
optional and are not required to operate the system. They are only
used to have time allow or cause an action. Time windows may be
summarized as follows:
Scheduled events are based on time windows, which are simply
periods of time during which an event may take place.
A time window is defined by a "Start" time and a "Stop" time.
The system supports up to 20 time windows.
The windows are shared by all partitions, and are used when
programming time-driven events.
Preparing a Time Windows Worksheet
Fill out the Time Windows Worksheet (located near the end of this
manual) using the steps outlined below.
NOTE: The time windows described here are also used to control
other functions in your system. Your installer may have already
programmed some time windows to control system functions. If some
time windows have already been programmed, make certain that the
first time window number you use is higher than the last number
already programmed or you will overwrite your existing time
windows.
As an aid to understanding the procedures for filling out the Time
Windows Worksheet, assume that we want a time window that starts at
8:00 AM and ends at 5:00 PM and that this time window is number 1.
1. Enter the Start Time desired for the time window. Note that
if your system uses a 24-hour clock (i.e., 5:00 PM displays as
17:00) the time entered here must also be based on a 24-hour
clock, so add 12 to any entries that are PM.
