The built-in protection device may prevent the appliance from operating
at temperatures outside the above range.
If the humidity is more 80 %, condensation may form at the air
outlet. To prevent this, open the vertical ventilation flaps as wide as
possible (vertical relative to the ground) and set a high fan output.
Notice for the user: If your installer adds refrigerant, he enters the added
fill volume and the total amount of the refrigerant in the following table.

For installation at special locations (underground garage, mechanical
rooms, balcony or at any semi-open areas):
▶ First refer to the requirements for the installation site in the technical
documentation.
You can find information on operating the indoor units in the
corresponding operating instructions.
3.1 Operating mode conflict
When using multi-split air conditioners, all operating modes are
possible, but with the following special features:
If you operate more than one indoor unit, indoor units may go into
standby due to an operating mode conflict. An operating mode conflict
occurs when at least one indoor unit is in heating mode and at least one
indoor unit is in another operation mode at the same time (e.g. cooling
mode). Heating mode always has priority. All indoor units that are not in
heating mode go into standby due to the operating mode conflict.
Indoor units with operation mode conflict show "−−" in the display or the
ON indicator flashes and the timer indicator is on. See technical
documentation of the indoor unit for more information.
