and blocked if the measurement value is smaller than the target value+hysteresis
difference.
Automatic shading:
The automatic shading evaluates the input objects "brightness" and "position of the
sun" of a weather station. The moving position for the automatic shading is specified
here as well.
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
