2.Special mention

1)If this model is connected to AI-NET by network adaptor, the different check codes are displayed on the main remote controller (New check code display on new remote controller) and AI-NET central control remote controller (Current system check code display on the current system central control remote controller).

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

When the air conditioner stops and the error is 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.
