Abstract
An improved irrigation controller of solid state design utilizes a microcomputer which retains and executes a watering schedule input by a user through data input means. One of the parameters of system operation is the times of day in which irrigation will start when the current day is selected to be active. The controller of this invention uses a slide potentiometer having multiple sliders which may be moved in a single slideway for setting multiple start times determined by the slider positions. In addition, a hot post terminal is provided in the controller connected to ground. This terminal can be used to determine station assignment by touching the station wires to the terminal as power is applied along a common line to the actuating devices, i.e. solenoids, of the various stations.
