﻿A signal at the input with a time length between one and five seconds is rejected as invalid.

*Scene extension without storage function*: Closing the contact leads to simple retrieval of the scene. A long signal at the input has no further effect.

*Scene extension with storage function*: Closing the contact with a signal length shorter than one second results in easy recall of the scene. If the signal at the input lasts longer than five seconds, the device generates a save command. In the scene extension function, a storage telegram is in this case transmitted to the KNX.
