Parameter setting
Brightness and Wind Sensor KNX LW sl
• Status: 19.08.2021 • Errors excepted. Subject to technical changes.
6.4.1. Twilight threshold value 1-4
Threshold value
Set, in which cases threshold values and delay times received are to be kept per object.
The parameter is only taken into consideration if the specification/ setting by object is
activated further down. Please note that the setting "After power restoration and pro-
gramming" should not be used for the initial start-up, as the factory settings are always
used until the first call (setting via objects is ignored).
Select whether the threshold value is to be specified per parameter or via a communi-
cation object.
When the
threshold value per parameter
is specified, then the value is set.
When the
threshold value per communication object
is specified, the starting va-
lue, object value limit and type of change to the threshold value are then set.
With both of the methods for specifying the threshold values the hysteresis is set.
