A remote controlled multi-station irrigation system in which discrete radio signals are transmitted from a remote location for each different function to be performed. The system includes a controller with a central processor, individual station actuator circuits, and interface circuitry; a transmitter which preferably transmits in an FM dual tone multi-frequency format, and a receiver which decodes the transmitted signal to hexadecimal data. The controller is automatically converted from a local to a remote operating mode by the insertion of a connecting cable from the receiver. The controller can be operated in real time or programmed for future operation from a remote location. The receiver can also be adapted for conventional controllers by adding field actuator circuitry which is connected directly to the field wires, bypassing the controller during remote operation.
