Rain Sensor Ready (cont.)
DELAY FEATURE - When using the Rain Sensor Ready
feature, in conjunction with the rain sensor. It is possible
to set a delay in the controller to stop the automatic
programs from activating too quickly.
This feature is applicable to the stations nominated to be
controlled by the sensor. EG: Set to rain sensor “ON”, and
will only occur when the rain sensor is “WET”.
The reason for this feature is that the rain sensor itself
can dry out due to strong winds or warm temperatures.
Often the sensor will dry out in 24 hours or less and the
automatic watering cycles will start. The soil may still be
too wet in clay or loam situations and it may be desirable
to increase the delay time. This can be set at the
controller.
The delay can be set from 24 hours up to 96 hours and
will prevent any automatic starts from occurring for the
nominated delay period. At the end of the nominated
delay time, the controller will check the rain sensor again
and if it is still reading “SENS WET”, the delay time will
override the automatic watering programs and prevent
any start time from ocurring. This will continue until the
rain sensor is “DRY” and then the automatic programs
will start at the next available start time.
This delay is locked in the controller memory and will
activate any time the Rain Sensor is in the “WET” mode.
NOTE: Stations set at rain sensor “OFF” will continue to
water automatically, and any station can be watered
manually in “system test” or “rain single station” mode.

DELAY FEATURE - SETTING RAIN SENSOR DELAY.
Turn the dial to Rain Sensor Selection.
Press the
back
button.
The display will show OFF.
This means there is NO delay set for the rain sensor.
The sensor delay will increment in 24 hr blocks, so to set
the required delay, press button & 24 “Sensor Delay
Hrs” will be shown in the display:
If a 48 hr sensor delay is required, press again, a
maximum of 96 hours, (4 days), can be set.
To cancel or clear a rain sensor delay:
Turn the dial to Rain Sensor Selection, press the
back
button, followed by the button.
The display will show OFF Sensor Delay Hrs.
If a delay period has been set & the rain switch is WET,
the controller display will show
“SEN WET” and will show
the remaining delay time in hours.
This will continue to override the rain sensor until the
delay time has finished counting down, or unless you
clear the delay feature.
