 How to check
To display an error code or to confirm the operation status, the remote controller (wired remote controller and
central remote controller) is equipped with an LCD display, and the interface circuit board of the outdoor unit is
equipped with a 7 segment display. A self-diagnosis function is activated to find out the details of a problem with
the unit.
 Error code list
The table below shows the error codes. See the table for details of error codes.
• To confirm the code from the remote controller, see “Wired remote controller display” in the table.
• To confirm the code from the outdoor unit, see “7 segment display on the outdoor unit” in the table.
