Troubleshooting

In addition to the check code on the remote controller of the indoor unit, a trouble of the outdoor unit can be
diagnosed by 7-segment display of the control P.C. board of the outdoor unit. Make good use of this function for
various checks. After check, return each bit of Dip switch to OFF position.

Segment display and check code

* However, when there is an auxiliary code, the check code (for 3 seconds) and the auxiliary code (for 1 second)

are alternately displayed.
