Shading with slat blinds
During slat adjustment, the horizontal slats of the blinds are not fully closed; rather they are matched to the sun condition and set
automatically in such a way that the sun cannot shine directly into the room.
However diffuse daylight can enter the room between the slats and so provide glare-free room lighting. Slat adjustment of an
external blind prevents the entry of heat from sunshine into the room and, at the same time, reduces the cost of electricity for
room lighting.

Sun protection at high sun elevations
Shading is automatically controlled if the shading conditions on the relevant facade are
fulfilled: luminosity threshold > 40 klux and sun on the facade. To limit the number of trips,
the shading starts by fully lowering the blinds following the direction of the slats at 50 %.
The low position will be maintained as long as the shading function is activated, and
adjustments are made simply by orienting the slats depending on the position of the sun.
The slats are positioned almost horizontally, so that the sun does not directly penetrate the
room.
Position: 100 %
Tilt tracking: 50 %
Sun protection at medium sun elevations
The low position is maintained and the slats are re-closed a little more to prevent sunlight
from directly entering the room.
Diffuse daylight, however, can still continue to enter and so provide lighting for the room
(daylight use).
Sun protection at low sun elevations
The slats are automatically closed to an extent where the sun cannot shine directly into the
room.
Position: 100 %
Tilt tracking: 80 %
