Abstract
An improved irrigation controller is provided for selectively turning ON and OFF each of a plurality of sprinkler valve stations around a lawn or garden. The controller permits direct entry on a station-by-station level of the run time, number of cycles, and frequency of operation. The controller then permits both start time and no water days to be entered globally.
