Why does my Daikin VRV II-Q RQYQ8-48PY1B Heat Pump not cool or heat air well?

  If your Daikin Heat Pump isn't cooling or heating well, make sure that the air inlet or outlet of the indoor or outdoor unit isn't blocked by any obstacles. Also, check if the air filters are clogged and clean them if necessary. Ensure that the outdoor unit is not enclosed. Verify that the temperature is set correctly, the airflow rate isn't set to 'LOW', and the air diffusion is properly directed. Close any open windows or doors, and use curtains or shades to block direct sunlight. Note that the model must be selected to match the air conditioning load, especially if there are too many people in the room.

  If COOL-HEAT selection is disabled on your Daikin Heat Pump, and the remote controller displays 'UNDER CENTRALIZED CONTROL', use a remote controller with the option to select cooling operation. Alternatively, if the remote controller displays 'UNDER CENTRALIZED CONTROL' and a COOL-HEAT selection remote controller is provided, use that controller to choose between cooling and heating.

Why does a white mist come out from my Daikin VRV II-Q RQYQ8-48PY1B?

  A white mist coming from your Daikin Heat Pump during cooling operation may occur when the ambient humidity is high. Cleaning the inside of the indoor unit might help. It can also happen immediately after cooling operation stops, especially if the ambient temperature and humidity are low, or after the completion of defrosting operation when the system switches to heating.
