On the wired remote controller, central control remote controller and the interface P.C. board of the outdoor unit (I/F), a check display LCD (Remote controller) or 7-segment display (on the outdoor interface P.C. board) to display the operation
is provided. Therefore the operation status can be known. Using this self-diagnosis function, a trouble or position with error of the air conditioner can be found as shown in the following table.

Check code list

The following list shows each check code. Find the check contents from the list according to part to be checked.
• In case of check from indoor remote controller: See “Wired remote controller display” in the list.
• In case of check from outdoor unit: See “Outdoor unit 7-segment display” in the list.
• In case of check from AI-NET central control remote controller: See “AI-NET central control display” in the list.
• In case of check from indoor unit with a wireless remote controller: See “Sensor block display of receiving unit” in the list.
