•Unit No. and check code are displayed.

•In a case of error with auxiliary code, the check code and the auxiliary code are displayed alternately.

2.Special mention

•The check code of the remote controller is displayed only while the air conditioner is operating (Remote controller start button ON).

When the air conditioner stopped and the error has been cleared, the check code display on the remote controller also disappears.

However, if the error continues after stop of the operation, the check code is immediately displayed with restarting of the operation.
