During firmware updates, the network gateway stops communicating with the user interface. This results in an error code being displayed on the user interface. When the network gateway is fully upgraded, communication will be restarted and the error will disappear from the user interface. BRP069A6x: A temporary display of the error code "U8-01" is expected in the user interface. DRGATEWAYAA: A temporary display of error code "U4-66" is expected in the user interface.

In order to reduce the temperature of the heater, the fan runs for 60 to 100 seconds after the air conditioner stops running.
The defrost function activated during the heating programme removes the ice, which is converted into water or steam. A small amount of water is also evacuated during the heating programme.
The plastic parts of the air conditioner, such as the grille, make a squeaking sound as they expand or contract slightly due to the change in temperature.
To reduce excessive load during restart, the air conditioner does not operate for three minutes when the start (ON) switch is pressed immediately after the unit is turned off or when the operating program (setting) is changed by the remote control.
This water flow sound is produced by the refrigerant circulating inside the air conditioner. This sound is most likely to be generated when the defrost function is activated during the heating program.
When the airflow is set to LOW, the amount of airflow increases when the overload control is activated. ("Overload" is the condition in which the air conditioner operates under an excessive load. Overload can be caused by unclean filters.)
