Check method

On the remote controller (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 table below.

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 7-segment display” in the list.
•  In case of check from indoor unit with wireless remote controller: See “Sensor block display of receiving unit” in the list.
