If you use a wired type remote control,
error codes will appear on the remote control display.
INDOOR UNIT
ERROR DETECTION
If you use a wireless remote control,
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 control.
