Abstract

PROBLEM TO BE SOLVED: To cancel re-startup prevention, and to improve the properties of installation and service, by providing a means that operates a compressor, when a signal, by which the compressor can be operated, is transmitted to an indoor unit from a wireless remote controller, while a trial operation switch is being pushed within a specific time after a main power supply is turned on. SOLUTION: A trial operation switch 103 continues to be pressed within three minutes after a main power supply is impressed. Then, a signal with the condition, on which a compressor 116 can be operated, is transmitted from a wireless remote control 106. This signal is recognized by a microcomputer 105, and a compressor immediate operation signal is transmitted to a control signal transmitting means 109. The compressor immediate operation signal is received by a control signal receiving means 112, and then it is transmitted to the microcomputer 114. Then, a compressor operation signal is transmitted to a compressor operation signal transmitting means 115. When the compressor 116 receives the signal, the compressor 116 performs operation.
