Hey guys.
I am in a bit of a pickle, mostly because what I want is not considered "conventional" in the country I live in, so I have a hard time getting the advice I need.
I have a " VAILLANT ecoTEC plus VUW 26CS/1-5, 21 kW" boiler + "sensoCOMFORT VRC 720F" combo fitted to work with my UFH of a bit less than 100 square meter house (just ground floor.)
Now, the "initial design" was meant to have individual room thermostats linked to the system and used the boiler as just an heating device that would come On and Off as per demand. But until the initial plan was completed I have opted out of that idea and decided to go with sensoCOMFORT VRC 720F to benefit from modulating controls and weather compensation that comes with it, but the sad part is that the contractor had no idea hot to "link" them together, so they left and I am now trying to figure this out.
I guess my main question is how do I link the pump (see attached pictures) on the manifolds to the boiler controls, or do I even need that pump to be connected at all, if from what I understand right my boiler's pump should be able to handle the circulation of the ~100 square meter by itself?
What are my options for my current setup?

I have been offered by another contractor to try to install a relay that would supposedly link teh control of the manifold pump to the Vailant control system, but from what I understand an external pump can only be "linked" via VR71 wiring center?


- Can I ignore / disconnect the pump and let the boiler pump do the job so I can use sensoCOMFORT VRC 720F's features?
- Or, sShould I install a relay and see what happens?
