Why do roof hatches open up during a wind alarm instead of close?
Roof hatches must absolutely close during wind alarms. If that is not the case, you must check the following:
Generally speaking, with a value of 0, all drives must move to their idle position or starting position. If the drives leave the idle position when the value is 0, then the safety function also cannot be ensured. Therefore, check your connection to the Blind Actuator using the existing manual operation. Note: If the arrow is pointing upward, the drive will move to idle position. Roof hatches will close, for example!
