ABSTRACT:
An irrigation controller includes inputs for entry or selection of a watering program and a memory capable of storing the watering program. A plurality of station modules are removably received in a plurality of corresponding receptacles. Each station module includes a station module circuit for switching a source of electrical power to open and close at least one of a plurality of valves. A processor is connectable to the station modules when the station modules are inserted into the receptacles. The processor is capable of executing the watering program and sending commands to the station module circuits to open and close the valves in accordance with the watering program. A manually actuable mechanism allows a power signal to be applied to each station module circuit after the station modules have been inserted into their corresponding receptacles.
