Planning and application
Set preset position
The preset position can be changed very easily via a 1-bit telegram. To do so, the blinds are moved into
the required new preset position using UP/DOWN telegrams as well as STOP/slat adjustment UP/DOWN
telegrams. The new position is transferred to the memory of the device as a new preset position via a 1-bit
telegram.
Example
The blinds are moved into a preset position after a short push button action and the current position is
adopted as the new preset position after a long push button action.
If there is a bus voltage failure, the saved preset values are retained. During programming, it is possible to
set via a parameter if the saved values should be overwritten by the parameterized values.
8-bit scene
In the 8-bit scene, up to 64 scenes are managed using a single group address. An 8-bit scene telegram
contains the following information:

Scene number (1...64) and

Recall/save scene.
The JRA/S receives the telegram. All the outputs allocated to the received scene number via a parameter
move to the recalled scene position or save their current position as the new specified value for this scene
number.
A code table for the communication object Scene with all the possible combinations can be found in the
appendix.
Each individual output of the device can be assigned to up to eighteen 8-bit scenes. For each assignment,
the settings for the height and slat position of the blind/shutter can be undertaken directly using ETS
parameters.
