Abstract

The object of the present invention is to make it easy to separate a portion which takes charge of the operation control of an air conditioner from the air conditioner using a remote controller, and the essential points are that the control means of the air conditioner controls the operation of a compressor to make the room temperature detected by a first temperature sensing means approach to a set temperature set by a first temperature setting means, and further comprises a changeover switch, and a means for controlling the operation of the compressor based on a signal from the remote controller when the changeover switch is in a valid state; the remote controller disposed being detached from the air conditioner comprises a second temperature sensing means for detecting the room temperature and a second temperature setting means for setting a desired temperature and transmits a signal for controlling the operation of the compressor to make the temperature detected by the second temperature sensing means approach to a desired temperature set by the second temperature setting means to the control means.
