Program Advanced Options
The previous sections covered the basic con-
cepts of writing a Program from the VSX
controller keypad: Program, Schedule, Start
Time, and Station run times, as well as Blocks
and Events.
The Program Options provide additional power
and flexibility at the individual Program level.
They are:
Edit Program Name
Set Program % Scale
Cycles
Cycle Delay
Skip Days
Pump
Edit Program Name is covered in detail in the
section, “Naming a Program”, on page 16.
Set Program % Scale: This is one of the most
convenient and frequently used options in the
controller. In the Field Controller Settings
section, we described the “Main % Scale” (see
Set Main % Scale on page 11), which affects
the entire Field Controller.
“Program % Scale” allows you to reduce or
increase all of the Run Times in a single Pro-
gram by the selected percentage (from 1 to
250%, in 1% increments). This enables you to
quickly adjust the amount of irrigation for
weather or other conditions without changing
the basic program. At 50%, each Run Time will
only run half as long, and at 150%, each Run
Time will run one-and-half times as long.
When this Option is selected at the Program
level, it permits you to tailor certain plant areas
for local conditions. If you only want to adjust
the greens irrigation, for example, without
affecting the fairway irrigation, you would %
Scale just those Programs with greens sprin-
klers in them.
Important: The effects of % Scale at the Main
(controller) and Program levels are cumulative.
The controller looks first at the Program Scale,
and then at the Main scale, to calculate the
scaled run time.
In other words, if the original (or base) run
time of a station is 10 minutes, and the Pro-
gram % Scale is set to 150%, the scaled run
time would be 15 minutes. If the controller
Main Scale is then set to 50%, the net total run
time for the station would be 8 minutes. Frac-
tions resulting from these calculations are
always rounded to the nearest minute.
