Problem
The shading solution rises automat-
ically.
The shading solution automatically
lowers (sun threshold exceeded),
but at what seems to be the same
brightness (sunshine) rises again
after about 15 minutes.
No automatic lowering after manual
raising.
After the sun threshold was ex-
ceeded, the shading solution was
automatically lowered, and then
raised manually. After this, there is
no more automatic lowering, even
though the sun continues to shine so
that that the sun threshold is ex-
ceeded.
The automatic function does not cor-
respond to the desired threshold.
The shading solution moves down
too early or too late in response to
the sun protection function or to the
twilight function.

Remedy
Raise the sun threshold, turn clock-
wise (higher number).
The automatic function was by-
passed by the manual raising.
Use the manual/auto button to
switch the sensor into manual mode
(LED lights up briefly red), and then
press the manual/auto button again
to switch it back into auto mode (LED
lights up briefly green). If the
threshold is exceeded, the shading
solution will now travel down after
about 3 minutes.
At the time at which you personally
feel that the sunlight is too strong or
that the twilight threshold has been
reached, and that a downward or up-
ward travel should occur, turn the
sun or twilight threshold controller at
the relevant threshold regulator (sun
protection or twilight function) slowly
to the left or right, until the LED just
changes from red to green. The cur-
rent sunlight or twilight value is now
set. After about 3 minutes, the device
will now move up or down. In the fu-
ture the shading solution will always
move up or down under these light
conditions as the threshold value is
exceeded or fallen below.
