Hi all, i wanted to give you a brief update: In the meantime I have successfully built up the 2011 and 2016 layouts, see attached images. The respective freezers run almost error-free. Currently, with the help of HiassofT, i'm looking for a problem with the freezer if the backup battery is missing. As soon as this has been solved, I will implement my own layout and if this also works, i can start a small batch. So long Sven
