PURPOSE:To set many identification codes by a simple and low-cost structure. CONSTITUTION:The controller for an air conditioner comprises a microcomputer 8 for decoding and deciding a signal from a wireless remote control unit 1, and a contact 10 which can read an ON/OFF state by the microcomputer 8. When the microcomputer 8 receives a signal from the unit 1 when the contact 10 is, for example, ON, it does not decide to employ or not to employ the received signal by an identification code, stores the received code in the microcomputer itself or in a non-volatile memory, and uses it as the following identification code. Accordingly, many identification codes can be set by a simple operation and a low-cost structure in which the unit 1 is operated by turning ON or OFF the one contact, it is not necessary to set the code at each time of power interruption in the case of storing the code in the memory, thereby improving convenient operability.
