NEW! 5-year lithium battery (Rain Bird Exclusive) and non-volatile memory, keeps time, date and program schedule in case of power outage.
Superior surge protection — withstands nearly 3 times higher electrical surges than competitive controllers.
Rain Bird quality construction and components.
Fuseless, diagnostic circuit breaker identifies a station with valve or wiring problems and continues to water operable stations.
