PRO 2 2
DIAMOND SETTINGS
The DS, as we call it, is an automatic calendar setting after run times and start times are
entered. The DS will set the minimum days of the irrigation calendar. This is to protect
against overlapping within a program. After initial programming of the PRO 2, run times
and start times, the DS will not allow you to enter additional run times or increase the
budget so that it will exceed the current calendar days set.
If you are unable to increase run times, check your “total run time” in position 5. If the
“total run time” for that program is close to the number of current calendar days for that
program you may have to increase the number of calendar days to get the controller
to accept increased run times, increased water budget or adding more valves with run
times to that program. The same is true of increasing the water budget; the calendar
may have to be extended to accommodate the extended run times to allow the program
to complete its cycle.
The DS sets the calendar automatically as follows. The start time entered is calculated
as to how many hours past 12 midnight it is, for example an 8AM start time would be 8
hours from midnight or the start of that day, then the DS looks at total run times including
pause time and adds the time from midnight to the start
time together. If the total time exceeds 24 hours the calendar is set for two days,
If the total time exceeds 24 hours the calendar is set for two days, if
the total time exceeds 48 hours the calendar is set to a three-day calendar and so on.
The first day will be set as a STRT day (Start) the following day will be “run” days. The
day you programmed this program, automatically becomes day 1 of the calendar, for
example a three-day calendar programmed on Monday would look like the following:
Day 1 STRT would be Monday
Day 2 RUN would be Tuesday
Day 3 RUN would be Wednesday
Day 1 STRT would be Thursday
Day 2 RUN would be Friday
And so on; please note that any calendar not divisible by 7 will run on different days of
the week as the year progresses. If the above example were changed to a five-day cal-
endar the days 4 and 5 would show OFF.
Note: It is important to remember if the total run time of a program is under 23 hours
and 59 minutes; the DS automatically sets the calendar to one day. Even if the start time
is set to allow the program to run past midnight into the next day. The same is true if
multiple start times are used in the same program and the total runtime of the program
multiplied by the number of start times is under 23 hours and 59 minutes. The DS will not
allow multiple start times that total more than 23 hours and 59 minutes.
