Rooms are set to a comfortable temperature of approximately 22°C, with the dial set midway between 3 and 4.

To lower the temperature (e.g. 18°C) — turn the dial to midway between 2 and 3.

To raise the temperature (e.g. 24°C) — turn the dial to 3.

Temperature changes are gradual. Setting the radiator to its maximum will not heat the room any faster.

Each apartment has built-in ventilation for airflow. If you'd like fresh air in winter, open the window only slightly and for a short time — cold air will quickly lower the room's interior temperature.
