During operation, the fan motor in the outdoor unit may stop
running under high temperature.
During Fan Operation, if other Indoor Units are running on
Heating Mode, the fan may stop in order to prevent sending
heat wind.
4.7 Defrost in the heating operation
During heating operation, outdoor unit sometimes will frost. To
increase efficiency, the unit will start defrosting automatically
(about 2~10 minutes), and then water will be drained out from
outdoor unit.
During defrosting, both the fan motors in the outdoor unit and
indoor unit will stop running.
