The
optional
brightness
sensor
can
be
used
to
achieve
optimal
shading
of
the
interior
rooms
when
the
sunlight
is
very
bright
and/or
to
close
the
shutter
automatically
on
the
onset
of
twilight.
Use
the
suction
pad
to
attach
the
sensor
to
the
bottom
half
of
the
window
pane.
Clean
or
degrease
the
pane
at
this
point
before
attaching
the
suction
cap
to
enable
it
to
adhere
better.
The
timer
recognises
the
brightness
sensor
automatically
when
it
is
connected.
The
display
shows
the
brightness
scale
and
the
item
SENSOR
in
the
menu
SETTINGS.
Where
required,
the
sun
and
twilight
function
can
be
activated
or
deactivated
separately
in
the
item
SENSOR.
In
addition,
the
two
limit
values/threshold
values
can
be
amended
at
any
time
in
this
item.
The
sensor's
sun
and
twilight
functions
are
only
active
in
the
AUTO
and
HOLIDAY
modes
and
are
shown
in
the
display
with
the
symbols
"Sun"
or
"Moon".
The
positions
of
these
symbols
on
the
brightness
scale
correspond
to
the
currently
set
limit
values
of
the
two
functions.
In
the
daily
sequence
the
die
sensor
functions
start
as
soon
as
the
shutter/blind
is
moved
up
for
the
period
of
the
preset
"Travel
time"
,
e.g.
triggered
by:
A)
the
UP
switching
time
of
the
time
program;
B)
manual
operation
(the
UP
or
COMFORT
buttons).
The
"Sun"
and
"Moon"
symbols
appear
in
the
display.
The
sensor
functions
are
ended
as
soon
as
a
DOWN
operation
for
the
period
of
the
preset
travel
time
is
concluded.
This
DOWN
operation
can
be
triggered
by:
A)
the
DOWN
switching
time
of
the
time
program;
B)
manual
operation
(DOWN
button);
C)
the
sensor's
twilight
function
The
"Sun"
and
"Moon"
symbols
then
disappear
from
the
display.
Sun
function
If
external
brightness
measured
by
the
sensor
increases
during
the
day
above
the
currently
preset
limit/threshold
value
"Sun",
the
sun
symbol
starts
to
flash
immediately.
If
the
external
brightness
remains
permanently
above
the
"Sun"
limit
value
for
the
next
10
min.,
the
sun
symbol
shows
constantly
after
expiry
of
these
10
minutes
and
the
shutter/blind
moves
to
the
preset
Comfort
position
(partly
lowered).
If
the
measured
external
brightness
falls
below
the
"Sun"
limit
value
in
the
further
course
of
the
day,
the
sun
symbol
starts
to
flash
again.
If
the
external
brightness
remains
permanently
below
the
"Sun"
limit
value
for
the
next
10
min.,
the
shutter/blind
moves
up
on
expiry
of
this
time.
The
Sun
function
can
be
carried
out
several
times
a
day,
depending
on
the
change
to
the
external
brightness.
Twilight
function
If
the
measured
external
brightness
falls
in
the
course
of
the
day
(e.g.
evening)
below
the
"Twilight"
limit/threshold
value,
the
moon
symbol
starts
to
flash
immediately.
If
the
external
brightness
remains
permanently
below
the
"Twilight"
limit
value
for
the
next
10
min.,
the
moon
symbol
shows
constantly
after
expiry
of
these
10
minutes
and
the
timer
triggers
the
command
to
move
down
(the
shutter/blind
is
closed).
The
sensor's
Twilight
function
is
independent
of
the
DOWN
switching
time
in
the
time
program,
i.e.
the
shutter
can
be
automatically
closed
with
the
DOWN
switching
time
of
the
time
program
or
through
the
Twilight
function.
