Sun protection
The sun protection function enables a blind to be lowered automatically in strong sunlight. If a set sun protection value is exceeded for more than 2 minutes, the sun sensor sends the 'sun protection' scene and the blinds move to their previously saved sun protection position. If the brightness drops below the set sun protection value for more than 15 minutes, the blinds move back up.
Temperature-dependent sun protection
Temperature-dependent sun protection can be used primarily in the colder seasons. The interior is only shaded when the set temperature value is exceeded in addition to the sun protection value. Once the sun protection has been triggered, the temperature analysis is deactivated.
Twilight
When darkness falls, the twilight function enables a blind to be lowered automatically or the lighting to be switched on. If the temperature falls below the set twilight value for more than 4 minutes, the 'twilight' scene is called up. If the set twilight threshold is exceeded for approx. 15 minutes, the blinds move back up or the lighting switches off. To allow the blind to be raised automatically at dawn, the sun sensor must be positioned so that it is not shaded by the blind.
