I have Viessmann colour signals 4010/4011/4012 etc with control boxes like 5220/5222/5210/5221 and push button panels like 5547 etc.
I use MS2 to run Marklin trains on my C track .
I installed these signals and with push buttons and related control boxes they operate and show RED/ Green lights and change over.
However, with the diagram of connections sent by Viessmann for Train control,i tried and retried those connections .
I ist connected without Reed as shown in diagram ( thinking that since i use push button which changes the colour setting ) and then with reed as well but my trains do not stop/start . Even the system stops.
I have had successfully installed Marklin 73 *** series signals and they work well to control train as stop/start. and earlier marklin 70** series too
Can any one suggest why I am facing this problem with Viessmann signals.?

I do not have url to show connection figure here as sent by viessmann.. but the source is here
