Scenes
When commissioning the plant, the softkeys of the central apartment unit
(switching groups 1 – 4) can be programmed for triggering scenes (scene
symbol appears on the display of the key assignment).
Scenes can be used to store certain states of all actuators involved and to re-
trieve them again, if desired. One example would be the differently dimmed
lights and the blind positions that you would consider adequate for a certain
event / at certain times.
