Viessmann 222-F fault code BD on heating circuit H2

Having connected the Vitotrol 200 RF to heating circuit H1 and then to H2, then deciding to leave it connected to H1.

H2 is still looking for the remote and is showing fault code BD, I can't find where in the coding I can tell the boiler H2 is no longer on a remote?

I can clear the H2 BD code by connecting the remote to H2, but then H1 throws up a fault BC.

Which ever circuit does not have the remote connected, is restricted at the oiler to adjuts the temprature, it is suggesting this is done by remote.

Any help would be appreciated.

Thanks
