Thanks for your answer. I'm happy to know that someone had already solved the problem :) Just a question: there is no difference between the 3 options "encoder": 1, 2, 3. But that's okay: the 0 button marks the counterclockwise rotation and button 1 the clockwise rotation. P.S. sorry for the delay in the response.
