Brightness:
------------------------------
For controlling brightness, a 1bit object (smaller or larger than a threshold value), as
well as two or three 16bit objects (measurement values, e.g. East, South and West sun)
can be used.
1 x 1 bit input object:
Set the delay times for shading (prevents constant opening and closing when light
conditions change quickly).
1 x 16 bit, 2 x 16 bit or 3 x 16 bit as an input object:
The brightness threshold value can be specified per parameter or communication
object. For several brightness measurement values (2 x 16 bit or 3 x 16 bit) only the
maximum brightness value is compared to the threshold value.
Threshold value per parameter:
Set the threshold value and delay times for shading (prevents constant opening and
closing when light conditions change quickly).
Threshold value per communication object:
The threshold value is received via the communication object and can be changed
additionally (e.g. button for "more sensitive" and "less sensitive"). Set the delay times
for shading here (prevents constant opening and closing when light conditions change
quickly).
