Vaillant 938, Tado and UFH

I currently have a Vaillant 938 boiler and plan to have ufh installed so that a wiring centre controls the actuators for each of the ufh zones and a separate 'zone' for normal radiators for the upstairs central heating.

In order to modulate the boiler to deliver the correct heating flow temperature, e.g. 30-50c for ufh and 50-70c for gch, is this doable using the Tado extension kit and Tado smart TRV's that I have integrated with the UFH and Vaillant 938 so that I can take advantage of the eBUS modulation.

Any ideas or suggestions ?
