Error Codes - Fujitsu ASYG 18 KLCA Installation Manual

14. ERROR CODES

If you use a wireless remote controller, the lamp on the photo detector unit will output error
codes by way of blinking patterns. If you use a wired remote controller, error codes will ap-
pear on the remote control display. See the lamp blinking patterns and error codes in the
table. An error display is displayed only during operation.
The error code table contains errors irrelevant to this product as well.
