Correction
Relocate the sensor to a more appropriate location.
Clean the debris off the Debris Screen. Remove the Tipping Rain Bucket from the sensor housing.
Clean with mild soap and water. Verify that the tipping mechanism is functioning properly and
reinsert the mechanism into the sensor housing.
Clear the funnel.
Set the dial to SPECIAL FEATURES and run the Short Circuit Test to identify short conditions and
repair accordingly.
For ET and Drip zones set the dial to FINE TUNE WATERING and decrease watering by up to 60%
in 1% increments. For Time-Based zones adjust the run time for the affected zone(s).
For ET and Drip zones set the dial to FINE TUNE WATERING and increase watering by up to 60%.
For Time-Based zones adjust the run time for the affected zone(s).
Set the dial to INPUT ZONE INFORMATION and change the soil type and/or degree slope.
Verify that the temperature sensor is not being heated by an air conditioner or reflective surface.
Relocate the sensor in a different location to more accurately measure the ambient temperature
of the site.
Verify that the Rain Gauge is not receiving runoff from the roof, trees, etc. Check the mounting
bracket is secure and not swaying back and forth.
If this is an occasional occurrence, the controller will finish the required irrigation during the
next allowed watering day. If it is a regular occurrence, expand the Watering Window using
CONFIGURE CONTROLLER. Another solution is to reduce the soak time for the affected zones.
If irrigation is desired at this temperature, set the dial to the SPECIAL FEATURES, select "Adv.
Controller Setup" and change the user set value (Temp Below) to a lower threshold temperature
value.
If irrigation is desired at the current rainfall amount, set the dial to SPECIAL FEATURES, select
"Adv. Controller Setup" and change the user set value (When Rain Reaches) to a higher rainfall
threshold.
