8-2-5. Diagnostic Procedure for Each Check Code (Outdoor Unit)
1) This section describes the diagnostic method for each check code displayed on the wired remote controller.
2) In some cases, a check code indicates multiple symptoms.
In this case, confirm LED display on the outdoor unit to narrow the contents to be confirmed.
3) The check code on the wired remote controller is displayed only when the same error occurred continu-
ously by multiple times while LED of the outdoor unit displays even an error which occurred once.
Therefore the display on the wired remote controller may differ from that of LED.

When even one of D800 to D804 rapid flashing, it
indicates that an error occurred. When D800 to
D801 indicate slow flashing or when D805 flashes,
push and hold SW01 and SW02 for 5 seconds
or more simultaneously. The error display ex-

changes to slow flashing.
3) Push SW01 several times and change LED
