How to disable the open window detection function on the Klarstein Bornholm Single Smart heater?
Frequently Asked Questions - 11/04/2026
Response Notice-Facile

The Klarstein Bornholm Single Smart heater has an open window detection function that automatically activates when the temperature drops by 3°C or more in 2 minutes. When this detection is triggered, the device stops heating and the indicator (9) blinks.

To disable the open window detection function: The procedure is simple and straightforward. Press the button (4) (on/off) to completely turn off the device. Wait a few seconds, then turn the device back on by pressing the button (4) again. Once the device is restarted, the open window detection function will be disabled and the device will operate uninterrupted even if a window is opened.

Important: This deactivation is only active during this operating session. If you completely turn off the device and leave it for a long time before turning it back on, the open window detection function will be active again by default. Additionally, disabling this function will increase your energy consumption if you leave a window open while heating.
