The

is
for
controlling
dimming

by

dimming
commands.
The
following
parameters
are
visible,
when
a

is
chosen

objects
two
‐

dimming
When
a
pair
of
channels
is
parameterized
as
dimming
function,
two
objects
are
shown.
One
object
reacts
to
a
short
keystroke,
the
switching
object
“Dimming
on/off”,
and
the
other
object
reacts
to
a
long
keystroke,
the
dimming
object
“dimming”.
It
is
possible
to
parameterize
this
function
as
brighter/darker
or
as
darker/brighter.
The
first
function
belongs
always
to
the
first
input.
If
you
switch
this
parameter,
the
function
will
be
switched
automatically.
By
choosing
the
dimming
function
(channel
A/B)
as
brighter/darker,
the
function
reacts
in
this
way:
A
short
keystroke
at
input
A
switches
the
lights
on.
The
lights
are
switched
off
by
a
short
keystroke
at
input
B.
A
long
keystroke
dims
the
lights
step
by
step
until
releasing
the
long
keystroke.
The
lights
are
dimmed
brighter
at
input
A
and
darker
at
input
B.
The
universal
interface
starts
always
with
the
last
brightness
level,
before
switching
off.
The
step
size
is
set
fixed
to
100%
at
the
dual
surface
dimming.
It
is
a
start
‐
stop
dimming.
that
means
the
lights
are
dimmed
as
long
as
you
hold
the
button.
After
releasing
the
button
a
stop
value
is
sent,
which
stops
the
dimming
process.
So
you
can
dim
the
lights
with
only
one
keystroke
from
0%
to
100%
or
from
100%
to
0%,
by
pushing
the
button
long
enough.
