Changes in season and temperature generally require a
change in station run time to maintain a healthy land-
scape and conserve water. The season adjust feature
enables you to change the run time of all zones assigned
to a program, simultaneously up or down, in 10% incre-
ments – with just the press of a button. Adjustments can
be reduced to 10% or increased to 200% of the pro-
grammed run time of each station.
A 50% setting, for example, would decrease a 20-minute
station run time to 10 minutes. Increases however, work
a little differently. With any adjustment above 100%, the
GreenKeeper 212 will first increase the run time by the
adjustment percentage, then split the time in half and run
the watering program twice. This allows the water to
soak in instead of pooling or running off. For example,
adjusting to 150% would first increase a 20-minute sta-
tion run time to 30 minutes, then split the time in half and
run two watering cycles back-to-back with 15 minutes in
each operation. During operation the % symbol will flash
to indicate a multiple watering operation.
Note: All station run times are retained in the controller
memory and returned to their set value when the season
adjust is reset to 100%. The only time a station run time
will appear changed is during operation.
Turn the control dial to the
SEASON ADJUST posi-
tion. The season adjust display will be shown and
100% will be flashing.

PROGRAMs switch setting. If necessary,
