ABSTRACT:
The present invention includes an irrigation controller utilizing a “virtual” dial. In particular, the present invention contemplates an electronic programming and controlling interface that is controlled according to actuation of a simple on/off switch (i.e., a binary switch), preferably a push button. For example, in one embodiment, an irrigation controller is provided wherein a rotary dial is replaced with a circular liquid crystal display. The LCD contains segments peripherally on its screen that are energized according to the desired function selected by the user. The segment that is “on” at a particular time will correspond to visual indicia on the panel of the controller to inform the user which function is operable at that particular time. The user can then advance to the next segment on the LCD screen by pressing a button located elsewhere on the controller panel.
