4.7.2 Function description
Saving a scene:
The touch sensor sends a read request to Gr.adr.1 which is only answered by the
"Feedback in %" object and with Gr.adr.2.
Gr.adr.2 is not processed by the object "dimming value".
In contrast, the touch sensor receives the value and saves it for the appropriate
scene.
Calling up a scene:
The touch sensor sends the value saved for the scene to the % object with the sending address
Gr.adr.1.
The value of the object “dimming value” is further processed to set the output brightness.
Once the dimmer has set the requested value, it sends feedback to the object “Feedback in %”
depending on the configuration.
