Initial level, light-level
2 lux ... 1000 lux
sensor, external
This parameter is used to define which value the sensor works with until the
first value is received via the KNX bus.
Weighting, light-level
1 % ... 100 %
sensor, external
This value defines the extent to which the external value is weighted.
Max. variation from the
10 lux ... 1000 lux
setting
This parameter defines the precision with which the required level of light is
controlled. This is necessary because lighting is controlled in dimming steps.
Setting an insufficient maximum variation from the set level can therefore
sometimes result in a further "brighter" adjustment step exceeding the set
level and in a further "darker" adjustment step taking illumination below the
set level. This leads to light being dimmed or brightened all the time (i.e.
continuously fluctuating light level). If this is the case, the maximum permissi-
ble variation from the set level must either be increased or the dimming step
reduced.
Max. dimming step
0.5 %; 1 %; 1.5 %; 2 %;
2.5 %; 3 %; 5 %
This parameter is used for setting the maximum dimming "step" (this being
the maximum level by which a new dimming level may increase or decrease
from the previous level with constant-lighting control).
Note: the larger the "Max. dimming step", the larger the "Max. variation from
the set value" should be.
Send new dimming level
0.5 s; 1s; 2s; 3s; 4s; 5 s 2 s
after
This parameter is used for setting the delay after which a new dimming level
is sent in constant-lighting control mode. This ensures that even if actuator
dimming times are short they do not result in constant-lighting control pro-
ducing any abrupt change in light level that a room user may find unpleasant.
Lighting with
switch OFF
sufficient daylight
dim to minimum dim-
ming level
This parameter is used for selecting whether to switch the lighting OFF
completely when constant-lighting control is activated and there is sufficient
daylight or whether to leave it ON but dim it to the selectable "minimum
dimming level".
switch OFF: lighting is switched OFF if the dimming level remains dimmed
at the minimum level for a specific period. If stay-ON time elapses first, the
output switches OFF directly.
dim to minimum dimming level: lighting remains switched ON and is dimmed
to "minimum dimming level" even if the dimming level measured by the
light-level controller is below the "minimum dimming level" selected. It is only
brightened again when the dimming level measured by the light-level control-
ler is above the "minimum dimming level" selected.
Minimum dimming level
0.5 %; 1 %; 2 %; 3 %;
4 %; 5 %; 6 %; 7 %;
8 %; 9 %; 10 %
If constant-lighting control measures a dimming level below the level selected
here, lighting remains dimmed at the minimum dimming level.
Basic illumination
inactive
Basic illumination
active
If required, the output can either be set to provide basic illumination either for
a limited period at the end of the stay-ON time or always when the light level
falls below a threshold.
Factory setting

Basic illumination ON
100 %
time-limited: at the end of stay-ON time, the output switches lighting OFF
and checks the level of light for max. 5 seconds. As soon as the target level
or threshold level is below the selected light level, basic illumination switches
ON for the parameterised time. If the light level measured is above it, lighting
30
stays OFF.
light-level dependent: if the measured light level is below the setting and the
output is not switched ON, basic illumination is activated.
always: basic illumination is always active when the output is not switched
ON.
Basic illumination
dimming level
This parameter is used for setting the dimming level at which basic illumina-
tion is switched ON.
Basic illumination
2 %
ON period
Basic illumination is switched OFF after expiry of the ON period that is set
here.
The ON-period can be set from 00:00:10 to 18:12:15.
Basic illumination
threshold level
This parameter is used for setting the threshold at which basic illumination is
activated if the threshold is not met, and at which it is deactivated again if the
threshold is significantly exceeded. This takes place irrespective of whether
persons are present in the detection zone or not.
Day night parameters
switch OFF
Day night parameters
When day/night switchover is activated, the parameter setting can be
switched over via an input object.
Stay-ON time, constant-
lighting control
Stay-ON time is started if no presence is detected. This has the purpose of
preventing the output from switching OFF immediately if the room is vacated
for a short time and having to be switched back ON again when a person
returns to the room.
Stay-ON time can be set from 00:00:10 to 18:12:15.
Light-level setting
This parameter is used for selecting the setting for light level control.
Automatic starting value
0.5 %
Yes: the sensor automatically determines the starting value after artificial light
calibration.
No: the sensor always starts with the given starting value.
Starting value, dimming
level
This parameter defines the ON level when constant-lighting control is started.
inactive
Lighting with
sufficient daylight
This parameter is used for selecting whether to switch the lighting OFF
completely when constant-lighting control is activated and there is sufficient
daylight or whether to leave it ON but dim it to the selectable "minimum
dimming level".
switch OFF: lighting is switched OFF if the dimming level remains dimmed
at the minimum level for a specific period. If stay-ON time elapses first, the
output switches OFF directly.
dim to minimum dimming level: lighting remains switched ON and is dimmed
to "minimum dimming level" even if the dimming level measured by the light-
level controller is below the "minimum dimming level" selected. It is only
brightened again when the dimming level measured by the light-level
controller is above the "minimum dimming level" selected.
