vaillant 618 controls

fitting boiler to existing system (s plan) i am bit confused with what controls to use, the boiler is located in kicthen with cylinder & motorised valves in airing cupboard upstairs, i intend to fit a vr65 control center in airing cupboard to connect cylinder stat & valves and vrt360f in hallway is this possible as both units connect to E Bus terminals in boiler can 2 devices connect to this terminal ?
The vr65 also requires a 240v supply should this supply come from the same spur as boiler supply so whole system will isolate from one point, this spur will be located next to boiler

The answers are

(1) Yes
(2) It doesn't matter, whichever is most convenient. If you do end up powering the VR65 from downstairs remember that the mains and ebus cables should have separation.

VR65 should have its own fused isolator. It doesn't matter where you connect the ebus cables, boiler, VR65 or even a joint box somewhere, as it is only digital info going back and forth between each component.
