11. ERROR CODES
If you use a wired type remote controller, error codes will appear on the remote control-
ler display. If you use a wireless remote controller, the lamps on the IR receiver 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.
For more details, refer to the installation manual of the remote controller.
