Wind speed and move behavior
The thick black curve represents the course of the wind speed. The horizontal line
represents the limit set by you for moving the sun protection up. The vertical
dashed lines mark the delay periods for activating and de-activating. Let us
assume that you have set 5 seconds for the activation delay period and 2 minutes
for de-activation delay period, then the sun protection reacts as follows:
The wind speed increases until Point 1 of the curve is reached. The limit for
moving the sun protection up is reached here. The "UP" delay period now begins
to run so that your sun protection is not yet moved up. At Point 2 of the curve the
speed drops below the limit for moving up. The delay period is now canceled
before it has expired and your sun protection has remained below.
Later on the wind speed increases again and exceeds the limit once more at Point
3. The "UP" delay period now begins to run again so that your sun protection is not
yet moved up. However, the delay period has already expired at Point 4 and the
limit is still exceeded - the sun protection now moves up.
The wind now drops again and its speed drops below the "Up" limit at Point 5.
Nothing happens yet, because the de-activation delay period now first starts - the
sun protection therefore does not travel down yet. At Point 6 the de-activation
delay period has finally expired and the speed still lies below the limit. The wind
monitoring function now enables the operation of the sun protection again.
The correct setting of the delay periods thus results in a comfortable control of
the sun protection. It contributes to "smoothening" the reaction behavior of the
control system. This ensures that the sun protection is not moved immediately
whenever the wind speed changes.
