Since shutter actuators always use a 1 signal for the down movement and a 0 signal for the up
movement, the button also emits this. It is also possible to change the action for long and short
keystrokes. It is thus possible to select whether to move via a long or a short keystroke. The
stop/step object then adopts the other operating concept.

MDT Single Object Control:
MDT Single Object Control enables a new operating concept for controlling roller shutters. For use,
the following parameter has to be set to active in the MDT shutter actuator to be controlled:
Now it is possible to start the up/down movement with a short keystroke and also to stop an active
up/down movement with a short keystroke.
Using the setting "Short = Up/Down/Stop / Long = Central object", an additional object is displayed
which can start the up/down movement with a long push-button action and can also stop an active
up/down movement with a long push-button action. This function can be used, for example, to move
an individual shutter in a room with a short push-button action and to move the entire room with a
long push-button action
