Season Adjust % Feature
Note: The Season Adjust % and Rain Delay features
modify controller operation only and do not change the
controller's programmable memory.
The Season Adjust % feature enables the station time of
all stations (assigned to a watering program) to be simul-
taneously decreased or increased from 10–200% in 10%
increments (100% equals no adjustment).
For example, setting Season Adjust to 50% decreases
all stations to half of their programmed station time. A
station programmed for 20 minutes would run 10 min-
utes and a station with 15 minutes would run 7 minutes
and 30 seconds. As a conservation measure, an adjust-
ment above 100%, first increases station run time, then
splits the time in half. The program watering cycle then
runs through twice consecutively. This method of
increasing irrigation enables irrigation water to soak into
the plant root zone instead of pooling and running off.
For example, adjusting to 150% will first increase a
20-minute station time to 30 minutes (1.5 x 20 = 30). The
controller automatically divides 30 minutes in half and
runs the station for 15 minutes in back-to-back watering
cycles.
Note: All station times are retained in the controller's
programmable memory and returned to their set value
when season adjust is reset to 100%. The adjusted
station time will be displayed during operation.
The % symbol will be displayed when an when the
Season Adjust % feature is utilized.
