Remote control for air-conditioning apparatus

Abstract

A remote control for an air-conditioning apparatus that includes an outdoor unit and an indoor unit connected to the outdoor unit by a pipe to condition air in an indoor room, the remote control being configured to bi-directionally communicate with the indoor unit, the remote control comprising: a first segment display part in which two or more seven-segments are arranged; a second segment display part in which two or more seven-segments are arranged; and a controller, wherein, in a failure mode in which a failure in either the outdoor unit or the indoor unit is diagnosed, the controller makes the first segment display part display a transmission code indicating which of the outdoor unit and the indoor unit is diagnosed to thereby identify a failure, and makes the second segment display part display an error code representing diagnosis content for the outdoor unit or the indoor unit.

1 . A remote control for an air-conditioning apparatus, the remote control being used for the air-conditioning apparatus that includes an outdoor unit and an indoor unit connected to the outdoor unit by a pipe to condition air in an indoor room, the remote control being configured to bi-directionally communicate with the indoor unit, the remote control comprising:
 a first segment display part in which two or more seven-segments are arranged;   a second segment display part in which two or more seven-segments are arranged; and   a controller,   wherein, in a failure mode in which a failure in either the outdoor unit or the indoor unit is diagnosed, the controller makes the first segment display part display a transmission code indicating which of the outdoor unit and the indoor unit is diagnosed to thereby identify a failure, and makes the second segment display part display an error code being sent from the indoor unit and representing diagnosis content for the outdoor unit or the indoor unit.   
     
     
         2 . The remote control for the air-conditioning apparatus of  claim 1 , wherein the second segment display part is larger than the first segment display part. 
     
     
         3 . The remote control for the air-conditioning apparatus of  claim 1 , wherein, in a normal mode in which the air-conditioning apparatus performs air-conditioning operation, the controller makes the second segment display part display a set temperature for the indoor unit. 
     
     
         4 . The remote control for the air-conditioning apparatus of  claim 1 , wherein, in a normal mode in which the air-conditioning apparatus performs air-conditioning operation, the controller makes the first segment display part display a current time or a timer time. 
     
     
         5 . The remote control for the air-conditioning apparatus of  claim 1 , to comprising:
 a wind speed display part having a plurality of segments to display speed of air sent by the indoor unit; and   a wind direction display part having a plurality of segments to display a direction of the air sent by the indoor unit,   wherein the controller makes all the segments of the wind speed display part and the wind direction display part light up during the failure mode.
