NORMal aIR CONdITIONER FuNCTIONS/SyMPTOMS
The following can occur during operation and are entirely normal.
Compressor protection
During starting/power outages, there is a 3 – 4 minute delay before the compressor starts. This is to protect the compressor.
Cold convection protection
The unit is designed to not blow cold air in HEaT mode when the indoor unit's heat exchanger is as set out below and has not reached the
set temperature:
a) When HEaT mode has just started.
b) When defrosting.
defrosting
• If the outdoor temperature is low and the air humidity is high, frost can form on the outdoor unit during the heating process. This decreases
the unit's heating effect.
• When defrosting starts, the unit switches off heating and automatically begins defrosting.
• depending on the outdoor temperature and the amount of frost on the outdoor unit, the defrosting cycle can take from 4 to 10 minutes.
• The indoor unit's fan switches off when the unit is defrosting.
• The time between defrosting cycles varies with the indoor/outdoor temperature and air humidity.
a white mist from the indoor unit
• In an indoor environment with rather high air humidity, a white mist may come from the indoor unit. This mist can arise if, in COOl mode,
there is a large temperature difference between the air intake and the air outlet.
• Mist may also appear owing to the moisture arising from defrosting when the air conditioner starts in HEaT mode after the defrosting cycle.
Noise from the unit
• you may hear a quiet hissing noise when the compressor is running or has just stopped.
• you may also hear a clicking noise, e.g. in connection with defrosting/starting. This may be because the indoor unit's heat exchanger is
expanding/shrinking owing to rapid temperature changes. These can generate gentle stresses in the indoor unit.
a distinct odour from the indoor unit
• This can be caused by the indoor unit giving off odours that have spread from building materials, furniture or smoke.
The unit switches to only FaN mode
• When the unit reaches the desired indoor temperature, the compressor stops automatically and the unit switches to FaN mode. The
compressor starts again when the indoor temperature rises/falls above/below the set temperature.
The heat pump is not generating as much heat
• as outdoor temperatures fall, the unit will produce less heat just as the indoor need rises. adjust your basic heat source (e.g. the building's
electric radiators) so that this system can work together with the heat pump. It should be adjusted to around 1 – 2°C below the temperature
set for the heat pump. This is to ensure good operation/defrosting.
Restarting after a power outage
• When power returns after an outage, the unit restarts automatically with (thanks to the unit's memory function) all previous settings.
