PURPOSE:To so improve an operability as to display a self-diagnosis result by starting a self-diagnosing circuit by an operation of a switch having a high operating frequency. CONSTITUTION:When a drive/stop button is pressed to energize a power source, a drive command and a self-diagnosis request signal is output to an air conditioner body. When the body receives it, a microcomputer self-diagnoses, and sends a signal of a self-diagnosis result to a remote controller side. The controller side receives this result, decides reception code analysis and a trouble code, and displays a trouble content. When there is no trouble, it displays a driving state of the conditioner.
