Automatic control
Using the automatic control it is possible to realise a comfortable automatic
sun screening system as well as to feedback the status of the shutter.
4.3.3.1
Automatic
sun protection
Function
Together with other KNX components, e.g. JSB/S, a very comfortable
automatic sun protection control can be established with the RM/S.
For example, the blinds can be moved upwards if the sunshine is very weak
or if the window concerned is in the shadows. As much light as possible is
thereby let into the room without any disruptive direct sunlight being taken
into account. If there is blazing sunshine on the window however, the blind is
lowered and the louvres are closed to the extent that direct sunlight cannot
penetrate the room. The residual opening in the blinds lets in a sufficient
level of diffuse light into the room.
