Description
The error which is occurring at present is displayed. LED
goes off while an error does not occur.
(Refer to table A)
After error status was eliminated, if you want to check
the error which occurred before, call this setting and
check it. (Even after turning off the power supply once,
you can recheck it.)
* This error display displays only the errors related to
compressor stop.
* In the case that an error occurred at present, the
same contents as that at present is displayed.
(Refer to table B)
You can check the room judged as error by operating
the miswiring (mispiping) check.
