If you use a wired type remote control,
error codes will apear on the remote control display.
When 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.
An error display is displayed only during running.
UTY-RNRYZ1
Double-digit error code means the error for
the indoor unit or outdoor unit.
