った。However, in such a conventional air conditioner, when the user operates the operation unit such as the remote controller by mistake and does not want to stop the heating operation, the user can stop the heating operation. When the delay operation is started, the delay operation is continued even if the restart operation is performed immediately, the compressor is temporarily stopped, and then the compressor breaks down when restarting due to the residual pressure of the refrigeration circuit. Since restarting is started after the restart prohibition time after stopping the compressor for about 2.5 minutes, which is provided to prevent the indoor unit, it takes a considerable time for the indoor unit to return to normal heating operation. In the meantime, there is a problem that the room temperature is lowered and the user feels uncomfortable.
