UFH schematic for electronic mixing valve with VR71

Current heating setup

Just realised and edited my post as you'd replied - thanks! From where should it be picked up from as per best practise? Can you nick it from the supply live?

Evening, Regarding zone valves and end switches - what does the 'PL' bit of PL 230 v on the drawing mean? It appears to be the supply for the switch on the zone valve, so is it 'permanent live' ? And from where should it be sourced as a best practise? cheers

Calling all VR71 owners! What voltage is present at the external demand input S6/S7/S8 terminals on the VR71? I'd like to add a 3rd party UFH system which uses these terminals to call for heat, so want to make sure that by connecting a UFH wiring centre which has a volt-free output, that this...

Hi folks, We're extending the house at present and I'd like to extend my current Vaillant home solution to accommodate 2 new UFH zones into the Vaillant system. The house is currently a basic 1 CH zone with manual TRVs and 1 DHW zone connected as S-plan. At present the following central...

Would rather have the appearance of the holes never being there. Blanks will do the job but it needs to be aesthetically pleasing also if at all possible. Wondering if this might do the job - might be an easier onsite task than welding...

I'd like to fill the tap holes in our cast iron bath but not sure if it's possible? My first thoughts were welding fillers in then re-enamelling the batch, but then thought about the liquid metal stuff I've used in the past instead of welding. Any thoughts on what the best thing to do might be...

Hi Degsy41, What did you do in the end about this? I am in the same position albeit with a VRC Four thirty and it would be helpful to know what you decided to do. Cheers Oldskoolskater
