Check codes and parts to be checked

Check method

On the remote control (Wired remote control, Central control remote control) and the interface P.C. board of the
outdoor unit (I/F), a check display LCD (Remote control) or 7-segment display (on the outdoor interface P.C. board)
to display the operation is provided. Therefore the operation status can be known. With 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.
• To check from indoor remote control: See “Wired remote control display” in the list.
• To check from outdoor unit: See “Outdoor 7-segment display” in the list.
• To check from indoor unit with a wireless remote control: See “Sensor block display of receiving unit” in the list.
