ABSTRACT:
An irrigation controller having multiple cancel modes invoked by depression of a single key. When no watering is taking place, a single depression of the key will cancel all watering scheduled to take place on the day the key is depressed. Two successive depressions of the key when no watering is taking place will cancel all scheduled watering. A single depression of the key while watering is taking place will cancel just the watering which is taking place, not the watering scheduled to thereafter take place on that or any subsequent day.
