ABSTRACT:
The present invention is directed to an irrigation controller, method and software program product for generating valve control signals for energizing a valve. The irrigation controller includes a valve actuation control module selectively coupled each of plurality of control nodes and generating a valve actuation control signal thereon. The valve actuation control signal is a continuous control voltage over a plurality of control signal periods for selectively energizing the selected irrigation valve. Also integrated in the irrigation is a valve chatter module for selectively coupled each of plurality of control nodes and generating a valve chatter control signal thereon. The valve chatter module selectively and, intermittently, energizes the selected irrigation valve. The irrigation controller may further include a remote controller of remotely controlling the irrigation controller.
