Programmable controller apparatus for irrigation systems
First Claim
1. A programmable controller apparatus for selectively activating a plurality of irrigation valves, the apparatus comprising:
- a housing unit;
at least one removable control module having memory capacity;
internal electrical circuitry confined within the housing unit for interfacing remote irrigation valves with the control module;
a power supply connected to the internal circuitry;
a rotary switch for selecting input/operational command modes for programming the control module;
a plurality of buttons for entering data into the memory of the control module;
a plurality of slide switches for selecting programming schedules and watering durations for a plurality of watering stations;
a replaceable control template removably positioned over a front facing of the control module, said control template having graphical depictions reproduced thereon for correlating programming interactions between the rotary switch, the plurality of input buttons, and the plurality of slide switches;
a display for displaying data entered into the control module, wherein said display toggles between a current time clock setting and an active watering cycle;
activating circuitry for selectively energizing the irrigation valves;
electronic circuitry for selectively activating at least one master valve and water pump to provide irrigation to one or more selected water valves;
manual programming means for selectively overriding watering sequences preprogrammed into the memory of the control module;
at least one external default-signaling means for providing visual warning of faulty irrigation valves;
means for expanding watering capacity of the programmable controller apparatus; and
a back-up battery power source for maintaining program integrity of the control module in the event of a power failure.

Abstract
A programmable controller apparatus and method for irrigation systems including at least one removable control module interfacing with internal circuitry of the programmable controller for activating and operating a plurality of watering valves. A housing unit is provided for the control module and the internal control circuitry of the programmable controller to prevent water contamination and unauthorized tampering. The removable control module interfaces with the internal circuitry of the controller to provide variations in programmable watering sequences for individual watering stations. The control module, in addition, comprises multiple programming keys and switches that provide interaction between the electronic programming and manual programming features which function in combination to provide easier programming options for the irrigation controller. Moreover, the stand alone capacity of the removable control module allows the control module to be programmed at a remote location from the irrigation controller. A manual mode of operation is provided for selectively overriding or deactivating previously entered programming sequences for individual watering stations without disturbing the programming sequences of other watering stations. A master valve is also included which can be selectively activated on a programmable basis for individual watering stations. Formed on the exterior of the housing unit of the programmable controller is an external default indicator that provides visual indication of faulty watering stations. Further thereto, a transmitter/receiver provides the programmable controller with radio compatible for on-site programming of faulty watering stations of the irrigation system.
