screen backlight turns off.
Long press the key ˄ and ˅ for about 5 seconds to

If the function has been activated from the advanced

the heating if the room temperature drops suddenly (default
setting 2°C in 15 minutes). This sudden drop of temperature

The device will return to its original operating mode after
30 minutes. The icon disappears from the screen. By
pressing any key, you will exit OWD mode.
