3 Operation
The device has 2 external inputs for buttons, switches, etc.
In the initial delivery condition, i.e. prior to KNX programming, the dimming actuator can
be operated directly with a button at I1.
Depending on the setting of the I1 external input in the ETS, the actuator can be operated in 2
different ways:
Control via bus telegrams.
This is the classic configuration for a KNX actuator.
The actuator is controlled exclusively via bus telegrams.
In this case, the external inputs I1 and I2 have no internal connection to the actuator.
Direct control (standard setting in the ETS)
The dimming actuator channel can be operated with a conventional button.
This is connected directly to the external input I1.
The input I1 is then used exclusively for this function and is no longer connected to the
bus in this configuration, i.e. there are no communication objects.
The actuator itself retains all of its communication objects in this configuration.
See chapter Typical applications.
