Help needed! Wiring on Worcester Heatslave oil boiler to UFH

[Al9955]

Hi everyone!

Hope someone can help, I’m installing a new boiler, it is a Worcester heatslave 2 external oil boiler, that is running into a heatmister UH8 wiring centre with hard wired Heatmiser V2 themostats (no rads) but my electrian couldn’t advise me on how to get it wired up!

So currently both have power so that the simple part, it’s the connection between the two that is the problem, so I have attached both wiring diagrams, so you have LS/E/LR on the wiring centre, then on the boiler you have pre wired links (LR) for both heating and water heating running into Live for the 230v out, just can’t find anyone to advise how to connect it right, the electrian told me the link wire should be 3 core and earth (which I have run) but not sure if that’s right!

Anyone advise at all?

Thanks in advance.

Boiler: remove the link between L and LR radiator. Link between L and LR tap must remain in place.

Boiler L -> Heatmiser LS
Boiler LR radiator -> Heatmiser LR
Boiler E (marked with the earth symbol on terminal block 9)-> Heatmiser E
Any unused cores in the cable should also be connected to E.
