10-2. Check Method
If an trouble occurs, the error code can be retrieved from the main remote controller/central remote controller (LCD
display) or the header unit interface P.C. board (7-segment display). Using this self diagnostic function, the trouble
can be identified using the table below.
Check code list
The following list shows all fault codes.
• If check code is from indoor remote controller: See “Main remote controller display” in the list.
• If check code is from outdoor unit: See “Outdoor 7-segment display” in the list.
• If check code is from AI-NET central control remote controller: See “AI-NET central control display” in the list.
• If check code is from indoor unit with wireless remote controller: See “Sensor display of receiving unit” in the list.
