Installed a Viessmann combi on Friday and couldn't get heating working. Hot water fine but not heating. Had a letter C on the display. Reset it and it went through startup and then went to C again. Called Viessmann technical and even they didn't know what it was.
Has anyone else had this and if so what is the cause.
Thanks

Viessmann been there today and said that the installer wired it up wrong and blew the PCB and that's the C symbol
