Abstract

An irrigation controller and valves incorporating an irrigation controller, which have user allocatable identification numbers, is disclosed. The controller and valves are programmed when to operate according to their identification number, and the program is uploaded and stored in each controller or valve as the case may be, together with clock data. The controller and valves then perform time keeping and operate according to the stored program. The controller and valves are intended to be battery operated, obviating the need to install wiring to connect the valves back to a central controller. This allows simplified installation and programming, and provides improved flexibility in programming of irrigation.

Abstract

A controller (11) in a tap timer, having a battery (19) for connected via a charge circuit (23) to selectively charge a storage capacitor C2. The storage capacitor C2 is connected to an actuator circuit (25) to selectively provide power from the storage capacitor C2 to actuate a device M1. A processor (13) controls the actuator circuit (25) according to a pre-programmed schedule or on user demand. The processor monitors various parameters including charge rate of the capacitor C2 in order to determine battery condition, to determine if the processor (13) should next actuate the device (13).
