<p>The present invention provides an irrigation controller (200) with at least one of several operator convenience features. One operator convenience feature selects for temporary execution as a group of the current pre-programmed irrigation schedule (300, 301, 302) and another pre-programmed irrigation schedule (300, 301, 302) that is not otherwise programmed to execute together with the current pre-programmed irrigation schedule. Another operator convenience feature includes a simple irrigation controller inputs (230, 231, 232) that add additional watering time to a current irrigation program. The additional watering time may include a single water application to each zone (310, 311, 312), multiple water applications (320, 321) to each zone (310, 311, 312) or single applications to some zones (311, 312) and multiple applications to other zones (310). A third operator convenience feature is that from any of several settings other than off, the irrigation controller automatically returns to the current irrigation program. Preferably the current irrigation program is at least partly derived from ETo data.</p> |
