Qubino Flush Shutter tilt position of the slats

Hello, I just got a Qubino Flush Shutter (ZMNHCD1). After calibrating it, opening and closing the blinds as well as setting the level seems to work. But how can I set the tilt position of the slats programatically? I use a C7 with the build in driver. Thanks

Anyone has some experience with the Qubino Flush Shutters?
