Abstract
An irrigation timer (2) includes a controller (8) coupleable to a power source (16), user inputs (12) coupled to the controller, controller output terminals (18) coupleable to an irrigation valve actuator (20) and an internal day-of-week and time-of-day clock. The controller may be pre-programmed with a predetermined, known initialization day-of-week and start time-of-day setting so that upon actuation, the clock automatically begins running at that setting, such as Sunday, 6:00 PM. The user inputs may have a single, preset function so that no user input is a multifunction input to help make programming essentially intuitive.
