the heating operation just starts
frost dissolving operation
operating under low temperature
Cold wind prevention (heat pump type )
Non-air-conditioner trouble
In the heating mode, the indoor unit won t send wind or operate in low wind ,if the heat
exchanger of indoor unit has not reached the stipulated temperature in the following
three states, so as to prevent the cold wind.
,
Frost dissolving operation (hot pump type )
The fan of the indoor and outdoor unit will stop under frost dissolving operation.
The time for frost dissolving varies in range of 4 to 10 minutes according to the out-
door temperature and the frost condition.
It is normal phenomenon that there may be steam coming out from the outdoor unit
during the frost dissolving operation.
When the temperature is low and humidity is high outdoors, the heat exchanger of
outdoor unit may frost, which may decrease the heating capacity. In such case, the air-
conditioner will stop the heating operation and convert to automatic frost dissolving,
and then resume heating after the frost dissolving finishes.
