Brightness Parameter - Used Brightness; Brightness Parameter - Use Object For Internal Brightness-Value Threshold - Busch-Jaeger mini KNX 6131/20 series Technical Manual

11.3.31 Brightness parameter — Used brightness
Options:
– Brightness-independent: The detector functions independent of brightness and will switch
during each movement.
– Only internal: The detector uses its own measured brightness and brightness-value
threshold internally to decide whether to switch on during movement.
– Only external: A 2-byte "external brightness" (input) communication object is enabled. The
detector uses this externally measured brightness (e.g., through an external brightness
sensor) and the "external brightness-value threshold" parameter (lux) to decide whether to
switch on during movement.
– Internal or external: The detector is activated only when the internally measured brightness
drops below the internal brightness-value threshold or the externally measured brightness
drops below the external brightness-value threshold.
11.3.32 Brightness parameter — Use object for internal brightness-value threshold
Options:
– No: There is no separate "internal brightness-value threshold" object.
– Yes: A 2-byte "internal brightness-value threshold" communication object (input) is being
enabled. This can be used to change the switching threshold at which the detector is
activated. The value is sent to this object in lux.
Note
The range of values lies between 0.5 – 1100 lux.
