•
The unit number, the alarm code and the unit code are alternately displayed on the set temperature section.
•
The unit number and the alarm code are displayed on the display of the outdoor unit PCB.
-
This alarm code is displayed when the voltage between terminal "P" and "N" of IPM is insufficient and the alarm has
three occurrences in 30 minutes. If the number of occurrences is smaller than two, the retry operation is performed.
The alarm code "06." Means fan controller abnormal operation.
