Error Codes - Hitachi R410A Manuel D'installation

12. ERROR CODES

If you use a wired type remote control, error codes will appear on the remote control display. If you use a wireless remote
control, the lamp on the photodetector unit will output error codes by way of blinking patterns. See the lamp blinking patterns
and error codes in the table below. An error display is displayed only during operation.
