hey all,
Based in South England, UK.
Hope this is the correct place to ask and that ive added all the required info/images.
I had an old boiler that was setup with my evohome system, 12 zones in my house, with controls on each radiator - all worked well.
Am i correct in thinking this IS opentherm? so it should work with my honeywell setup?
If so, I think my installer didnt connect the viessman to honeywell? So i want to first check it should work, before i ask them back to fix.
Currently they dont all talk and so its a nightmare trying to set the boiler to a temp and then have it work with the rads, as the outdoor temp and the whole heating curve things play havoc with it all!
im getting various errors, such as Viessman dhw heating flow rate not reached and high-limit safety cut out
Also, ive set my office to be 21, however its just staying at 18
even though the outside temp is 7.2 and the heating circuit 1 is set to be 21?
