FIG. 6 is a diagram showing a time chart showing the data displayed on the display means (6) of the remote control unit (1). In the case of A, the inspection points are displayed only during the time T and the passage of time. At the same time, the display is switched to the air conditioner number indicated by B, and the operation is automatically repeated continuously at predetermined time intervals and the operation is automatically repeated continuously at predetermined time intervals.

〔The invention's effect〕

As described above, according to the present invention, the inspection point detection means for detecting the inspection point when each part of the separation type air conditioner is abnormal and the air conditioner number registration for registering the air conditioner number are provided in the indoor unit control unit. Means to send the abnormality information created by the means to the remote control unit,
Upon receiving the abnormality information, the remote control unit automatically and alternately displays the inspection location where the abnormality has occurred and the air conditioner number at predetermined time intervals, instead of the information that is normally displayed. Since the switching means for selecting and switching to display is provided, the remote control unit continuously and alternately displays the inspection location and the air conditioner number from the received abnormality information at a predetermined time interval by the switching means. It suffices to select and switch to display and automatically display by the display means, the remote control unit can be made smaller and lighter, and information creation is performed in each indoor unit control unit, so that the system reliability is improved, In the event of an abnormality, the inspection location and air conditioner number are displayed alternately on the same display means, so the number of display elements can be reduced. Reduction is possible to reduce the display space, and which part is possible easily prompt service to recognize whether the abnormal effects of any air conditioner is obtained.
