SYSVRF AIR EVO HP Mini OM

The indoor unit of the intelligent inverter centralized air
conditioner can be controlled solely, but the indoor unit in the
same system can not run cooling and heating at the same time.
4.6 Features of heating operation
Warm air will not be blown out immediately at the beginning of
the heating operation, 3~5 minutes ago (depends on the indoor
and outdoor temperature), until the indoor heat exchanger
become hot, then blows out warm air.
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.
When the Cooling and Heating operation confront with each
other, the Indoor Unit which are running on Cooling Mode would
stop and there will be Standby or No Priority displayed in the
Control Panel. Those Indoor Units which are running on Heating
Mode will run continuously.
If the Air Conditioner Administrator has set running mode,
then the air conditioner can not run on modes other than the
presetted.Standby or No Priority will be displayed in the
Control Panel.
