Abstract

PURPOSE:To permit to control the air-conditioning machine having the same kind of code system surely by a method wherein the information of a remote control number is provided in a signal transmitted from transmitting side and a remote control number selecting means is equipped in receiving side. CONSTITUTION:When the switch 1 of the transmitting device is pushed, LSI 12 reads the number of switch as well as the information of a remote control number switching switch 13, checks the information of air conditioning and transmit the signal to a transistor 4. A signal is transmitted from an infrared rays emission element 3. The infrared light is taken into the receiving device through an infrared receptor element 6 and is taken into the signal reading circuit 9 of the LSI 18 through a detection circuit 7, then a decision circuit 15 decides whether the transmitted remote control number is coinciding with the remote control number selecting switch 14 or not. According to this method, the air-conditioning machines may be controlled surely and individually even in case the wireless type air-conditioning machines, having the same or the similar kind of code system, exist in the same room.
