Heatmiser and Vaillant heating controls. Fault diagnosis and repairs.

I thought that using the VR71 would negate the need for a 10 way wiring centre, seeing that you have a Heatmiser Wiring Centre also
Please provide more details on the relay and the VR10 pip sensor you mentioned shows up as either a tank or solar sensor. im sure alot of householders are stumped as to how to get Vaillant wiring centre and UFH wiring centre to work and maximise modulation

@@Anthony-dh3ty Hi, just a follow up question on this. For a home refurb project I have ufh setup on a single floor with 4 separate heating zones using all heatmeiser equipment - thermostats (neostat), neohub(Gen2), wiring centre (UH8-RF), actuators (on manifold). The boiler in place is Vailant ecotec plus 625. To achieve boiler modulation is only the VR71 needed in addition to the heatmeiser equipment I already have? Or do I need to replace the heatmeiser equipment with Vailant ones?
