A simple, inexpensive multi-station sprinkler controller has three pushbuttons: the first selects one of a plurality of predetermined combinations of watering cycle durations and repetition rates; the second selects a starting time, and the third initiates a manual cycle. On power-up, the controller defaults to a predetermined operating cycle and start time. A short circuit at any station stops watering and initiates a fault indication that identifies the short-circuited station. All status information is conveyed by the scrolling, illumination, flashing and/or blinking of one or more of a small set of LEDs. In another embodiment, a fourth pushbutton is provided to allow setting separate combinations for different stations. In a third embodiment, these functions are performed in a single-station controller by just two buttons and one LED.
