SET POINT USAGE TIMES.
Sets the 4 time set points associated with the control temperature set points and the
High and Low alarm temperature set points. The times can be any time of the day
(in
24 hour mode)
to the minute, with the following conditions. Time 1 must be the first
time after 00:00
(12 midnight)
followed by time 2 etc.. Once time 1 is set the unit
will not allow time 2 to be set to an earlier time and so on for all time set points. If
two or more time set points are set to the same time, the later
(if 2 and 3, time 3)
will
be the time
(and therefore the set point number)
used from that time until the next
time set point is reached. See also DAILY SET POINTS for information on the
usage of one or more set points that can be used on any particular day of the week.
