ELECTRONIC CIRCUIT BREAKER
The Sterling is equipped with an electronic circuit breaker. If the controller de-
tects a short circuit at a station (valve), it will shut the station off and the dis-
play will alternately flash “FUSE” and the station number or “0” for the master
valve. The controller will continue automatic operation at the other stations.
During future watering cycles, the controller will skip over the short¬ed station
until the short is repaired.
To clear the electronic circuit breaker, press the CLEAR key after you have in-
vestigated and corrected the cause of the short.
Remove the lower plate by removing the two screws that fasten it to the
controller enclosure.
Remove the four screws that fasten the main panel to the enclosure. Then,
maintaining a grasp on the panel, lower it about one inch and tilt the top
toward you to gain access to the battery holder on the rear side.
Remove the battery from the clip holder and replace it with a Panasonic 3M
BR2325, or equivalent.
