When reprogramming the control element, the values stored by the user can be
overwritten by the preset values in the parameterizing software. To do this, the "Overwrite
scenes for download" must be set to "activated". The values stored by the user remain
in the control element with the "deactivated" setting.
12.29.5 Extended parameter – Object type actuator group A..H
Options
This parameter is only adjustable if the "Number of actuator groups" is set to at least "2".
The size of the actuator group communication object can be adjusted for different
application cases under the "Type actuator group A..H" parameter. The following object
sizes are available:
- 1-bit switching, for the activation of switching functions or actuators
- 1-bit blind, for the activation of blind actuators
- 1-byte 0..100 %, for the activation of dimming actuators or blind positions (default setting)
- 1-byte light scene number for the calling up of additional actuator groups
- 2-byte temperature values absolute (-33.5°C to +93.5°C) for specifying a new default
value in room thermostats
12.29.6 Extended parameter – Scene number
Options
The "Scene number" parameter specifies with which value the Scene 1 or a scene
storage can be call up that is received on the 1-byte "Scene call-up" communication
object. An arbitrary scene number from 1 to 64 can be set.
12.29.7 Extended parameter – Scene can be saved
Options
The scene values that are stored in the control element and which are sent out via the
actuator objects can be overwritten by the user. If the "Overwrite scene for download"
parameter is activated, the user has the option of carrying out a scene storage. In this
case, read requests are sent to the connected actuators on the actuator objects for
receipt of a scene storage command. The values of the reply telegrams are stored in the
memory of the control element and overwrite the previously current values. These are
also not lost in the event of a possible power failure.
