KNX PARAMETER
SETTINGS
Monitor function
disabled/enabled
If enabled, the sensor activates the monitoring of presence
events.
Monitor
cyclic
time
[min]
0 .. 255 (0 = never)
Defines the sending period of the movement counter;
each time the counter is restarted from zero.
Simple presence
In this mode, the sensor acts as a simple presence
detector without taking into account the
contribution of the brightness sensor.
There are 3 communication objects that can send
data on the bus when the presence or absence
condition is detected, channels A and B are 1 bit,
channel C is configurable.
<Channel x> Output A
1 bit
CRT
< Channel x> Output B

< Channel x> Output C

1 byte signed
1 byte unsigned
2 byte signed
2 byte unsigned
2 byte float
For channels A, B, C it is possible to set the cyclical
repetition of the command; if activated the
command is sent periodically, in presence and
absence for all 3 objects.
Automatic
presence,
illuminance
depending
In this mode the sensor works taking into account
the contribution of the brightness sensor.
The parameters, functions and communication
objects are the same seen in the settings of the
simple presence mode plus some specific
parameters for the management of the on / off
control of the light.
[A]
The detector identifies a movement and activates
presence because the illuminance is lower than the
setpoint (the light is turned on)
[B]
The illuminance exceeds the setpoint value + the
hysteresis and the sensor goes into the absence
state (the light is turned off)
[C]
The illuminace becomes lower than the setpoint,
the presence status is still active (the light is
switched on).
[D]
The FOLLOW UP time expires without any new
presence detected, the sensor goes into the
absence state (the light is turned off)
KNX PARAMETER
SETTINGS
Average lux algorythm
Very fast
fast
Normal
slow
very slow
It defines the calculation speed of the average illuminance
value, the faster the algorithm and the faster it reacts to a
change in lux level. The "very fast" selection can lead to
very frequent switching on and off of the light, the "very
slow" selection can introduce delays in switching the light
on or off.
Upper
threshold
illuminance [*10 Lux]
Identifies the illuminance threshold to be set as a limit
value for switching on the light when presence is detected
(for higher illuminance values the light is not switched on)
Ignore
illuminance
threshold on presence
event
no / yes
This parameter defines whether, when detecting presence
with brightness above the threshold, the sensor must turn
on the light before starting the regulation (parameter =
yes) or not turn on the light (parameter = no).
