Viesmann fault code

[Rekusu]

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

Managed to solve this but now have a 00 fault code!
