  As shown in FIG. 5, when an abnormality of the minor classification “0” of “Error A” is detected, as shown in the column “Notification by indoor unit buzzer sound”, the speaker 120 outputs a short sound 1 A cycle of generating a long sound four times, generating an interval five times longer than a short sound, and generating a long sound five times is repeated with an interval seven times longer than a short sound. It is assumed that the sound of one long sound is three times longer than the sound of one short sound. For short and long sounds, there is an interval of one short sound pronunciation between the pronunciations. As described above, the speaker 120 uses “Sound” with “10” of “Failure No.” indicating the content of the abnormality as a Morse code and notifies.

  Further, for example, when an abnormality of the minor classification “3” of “Error B” is detected, the speaker 120 emits a short sound once and a long sound as shown in the “notification by indoor unit buzzer sound” column. 4 times, 3 times shorter than 3 times, 3 shorts, 2 times longer, 5 times longer, 3 times shorter, 2 times longer The cycle of generating is repeated with an interval of 7 times the short sound. It is assumed that the sound of one long sound is three times longer than the sound of one short sound. For short and long sounds, there is an interval of one short sound pronunciation between the pronunciations. As described above, the speaker 120 uses “Sound” as “Morse signal” for “133” of “failure No.” indicating the content of the abnormality.

  The frequency and volume of the short sound and the long sound are the same, and the sound generated by the speaker 120 is composed only of a combination of the short sound and the long sound.

  The user can bring the telephone 2 close to the indoor unit 100, call the service person or the service center, and inform the service person through the telephone 2 of the sound generated by the speaker 120. A service person who receives a telephone call from the user can listen to the sound generated by the speaker 120 through the telephone and accurately know the abnormality of the air conditioner 1.
