11.5.25 Extended parameters — Use of object for setpoint brightness
Options:
No
Yes
– No: There is no separate “brightness” object.
– Yes: A 2-byte “brightness setpoint” (input/output) object is being enabled. This can be used
to change the switching threshold, while the presence detector is activated or deactivated.
The value is sent to this object in lux.
Note
The value which can be sent lie between 1 and 1000 lux. If a value is sent that is
too small or too large, this value is adjusted to the limit value automatically:
– Value < 1 -> value = 1
– Value > 1000 -> value = 1000
11.5.26 Extended parameters — Use of object for saving setpoint brightness
Options:
No
Yes
– No: There is no separate “save setpoint brightness” object.
– Yes: A 1-bit “save setpoint brightness” (input) communication object is being enabled. This
can be used to save the current measured brightness with a 1 telegram as new control
threshold.
11.5.27 Extended parameters — Use of actual brightness object
Options:
No
Yes
– No: There is no separate “actual brightness” object.
– Yes: A 2-byte “actual brightness” (output) communication object is being enabled. This
object outputs the corrected measured brightness which is used by the constant light
controller.
11.5.28 Extended parameters — Cyclic sending of actual brightness
Options:
No
Yes
– No: The actual brightness is only made available for reading. The value is not sent
automatically.
– Yes: The actual brightness is sent each time to the "Actual brightness is sent every
(hh:mm:ss)" parameter. The value can also be read.
