Can I connect multiple UH8s running a 3core around all for heat enable?
Yes the UH8 heat enable is internally protected against back feed, wire all outputs in parallel.
Can I connect multiple UH8s running a 5 core around all for UFH valve ?
No. the UFH valve will back feed they must remain independent, if you have a common valve for the underfloor heating then use the heat enable to operate the valve and use the valve end switch to fire the boiler. The L E N valve connections remain unused but you need a wire link between OR and GR.
