Deactivation of the brightness measurement (the
brightness has no effect). The light channels only switch
after presence/absence. Possible with the „SendoPro,
theSenda B/App“ management remote control (measu-
ring off) or the “theSenda P” installation remote control
(button ).
Room correction factor mid, brightness measure-
ment value mid
The room correction factor is a measurement for the diffe-
rence of the brightness measurement on the ceiling and the
work area. The brightness value on the ceiling is influenced
by the installation location, the incidence of light, the position
of the sun, the weather conditions, as well as the reflection
properties of the room and the furniture.
With the room correction factor, the measured brightness
value of the channel C1 light is adjusted to the conditions in
the room and in this way can be matched to the lux meter
value
measured at the surface beneath the presence
detector.
Room correction factor = Brightness value at the ceiling
Brightness value on the work
surface
We recommend the following procedure:
The lux meter is placed on the work surface below the
sensor and the measured lux value is entered via the
„SendoPro, theSenda B/App“ management remote control,
<brightness measurement value mid> parameter.
The room correction factor is calculated from this
automatically. Values between 0.05 and 2.0 are permitted.
Calculated or entered values outside the permitted range
will automatically be set to the appropriate limit value.
The calculated room correction factor will be applied
immediately. For monitoring purposes, the room correction
factor can be queried via the <room correction factor mid>
parameter.
L
The standard value is 0.3 and is suitable for most appli-
cations. Changes are only sensible in strongly deviating
situations.
Detection sensitivity
The detector has 5 sensitivity increments. The basic setting is
the middle increment (3).
Increments 1 to 5 can be selected and sent to the detector
with the „SendoPro, theSenda B/App“ management remote
control. On the “theSenda P” installation remote control, the
sensitivity can be decreased by one increment each time the
button
-
is pushed or increased with the
button.

By selecting the test presence operating mode, the set sensi-
tivity increment is not changed.
Lighting time delay
Value range
Adjustable values with SendoPro, theSenda B/App
management remote control
10 s – 60 min
In the “theSenda P” installation remote control, the
following values are available
10 s (button
),
30 s, 60 s, 2 min,
10 min, 20 min,
60 min (button
)
Short presence
If someone goes into an unoccupied room only briefly and
leaves it within 30 seconds, then the lighting will be switched
off prematurely after 2 minutes (short-term presence). The
short-term presence can be used for the fully automatic and
semi-automatic configuration types.
The time delay is applied according to the set time delay.
Off
Short-term presence is active.
On
Energy saving mode eco/eco plus
The selection of “eco” stands for optimum switching behavi-
our, while “eco plus” stands for maximum energy saving.
Value range (with SendoPro, theSenda B/App)
“eco”
The time delay adjusts to the user behaviour by self-learning.
It does not drop below the set value.
“eco plus” The set time delay remains unchanged (no self-learning
effect). Faster response to brightness detection than with
“eco”.
Presence switch-on delay
The contact of the external DALI relay closes when some-
one is present regardless of the brightness and after the set
switch-on delay has elapsed. Buttons and the configuration
type (fully automatic device/semi-automatic device) do not
affect the relay contact.
Value range (with SendoPro, theSenda B/app)
No switch-on delay
0 s
Switch-on delay
10 s – 30 min
Presence time delay
The relay contact of the external DALI relay only opens once
the set time delay has elapsed in periods of absence.
