- The presence of condensate is due to the high level of humidity
in the room
- Check the connection of the condensate drain tube.
- Make sure the condensate drain is not obstructed.
- In Heating mode, condensate is normal on the outdoor heat
exchanger.
- In Heating mode with low temperatures, the condensate tends
to freeze. This frost is automatically removed by the unit by
activating a defrost cycle. In this case, the loss of water from the
condensate drain is normal.
- In Heating mode, to prevent jets of cold air, ventilation is active
only when the indoor unit heat exchanger is hot enough.
- In the Dehumidification mode, the ventilation of the indoor unit
may switch off to keep under control the inside temperature.
Check if the connector jumper contacts
properly. If the PCB is to be replaced,
please take off the old for the new PCB.
