Dynamic

wind
sensor
The
wind
sensor
enables
driving
the
shutter/blinds
up
at
a
certain
value
to
prevent
the
shutter/blinds
of
damages
at
storm
or
too
much
wind.
Limis

‐
24m/s
can
be
parameterized.
Furthermore
a
minimum
of
period
can
be
parameterizedfor
which
an
exceedance
or
an
undercut
must
be
measured.
So
a
high
frequently
switching
can
be
avoided.
For
activating
the
threshold
an
exceedance
must
be
measured
for
the
adjusted
time.
For
the
deactivation
an
underecut
must
be
measured
for
the
adjusted
period
of
undercut.
The
sending
behaviour
of
the
output
object
“Treshold
value”
can
be
parameterized
individually
in
consideration
of
the
sending
behaviour.
