Hi there,
Trying to tweak the UFH temps settings yesterday and somehow have come up with a 'ba' fault code on my Viessmann 200W boiler.
It's do do with the heating circuit, of which I only have one. But I cannot find how to set the correct heating circuit or how to cancel the fault code and light.
Grateful for any suggestions,
Thanks
Rex
