﻿This parameter defines the functionality of the scene extension.
Setting options when button is pressed and held:

*No reaction*: there is no particular reaction to a long press of the button.

*Storage function*: A storage command is generated by a button actuation for more than five seconds. In the scene extension function, a storage telegram is in this case transmitted to the bus. The internal scene is stored. The internal scene control module will then request the current scene values for the actuator groups used from the bus.

A button actuation lasting between one and five seconds will be discarded as invalid.

If the device is used as a scene extension, the scenes can either be stored in one or several other KNX devices (e.g. scene function of the gateway or light scene push button sensor).
When a scene is recalled, the device transmits a telegram with the respective scene number via the extension object of the button.
