10-2-4. Distinction of error mode by LED indication of outdoor unit

On the Type AP112, AP140 and AP160, a Dip switch (SW801) and LED are provided on the P.C. board of the outdoor unit.

Exchanging this Dip switch enables users to know the status of the outdoor unit in that time.

Lighting status of LED enables users to know the distinction stage before trouble of the outdoor unit will be determined and displayed on the remote controller.

Depending on the indoor unit to be combined, the error of the outdoor temperature sensor (TO) may be confirmed on LED indication only.
