<p>PROBLEM TO BE SOLVED: To provide a controller of a unit, which can simplify wiring operability even if the unit to be controlled exists in a remote position. SOLUTION: A controller, an infrared ray emitting element 76, the switching element 28 of a transmission side, which controls the infrared ray emitting element 76 based on data transmitted from the controller, a light receiving element 77 receiving an infrared ray from the infrared ray emitting element 76 and operating and the switching element 28 of a reception side, which controls a unit based on data generated by the operation of the light receiving element 77 are installed. The switch element 28 is provided with a switching means, a storage means holding self-ID code, a transmission/reception means transferring data with an outer part and a switch element side control means controlling the switch means based on data from the transmission/reception means.</p> |
