Application note
The external venetian blinds cannot be protected with wind sensors against sudden gusts of wind. Make sure that the external vene-
tian blinds remain retracted if a storm is imminent. Updrafts or fallwinds at facades could lead to the destruction of the external vene-
tian blinds. Wind sensors cannot detect these as a rule.
