An irrigation system for controlling a number of control valves (104) is disclosed. The valves (104) control the flow of water in a corresponding branch pipe (102) leading from a common supply pipe (101). The system uses wireless transmission of control signals to operate a control unit (115) which operates the corresponding control valve (104) from a corresponding power generator (107). The control signal is encoded by an encoder (118) according to predetermined conditions and is decoded by each of the control units (115), the coded signal being received by each control unit (115) and the specified control unit (115) operating only.
