Hi again think making progress ,could anyone give me a bit advice on the connections on my jguh1 to my boiler
on my boiler i have a boiler connector block it has neutral ,switch live ,live and earth inside it.on my ufh i have two connections labelled boiler enable .the boiler is a windhager biomass boiler with external pump thats wired to boiler any ideas ? The connector block is normally for the thermostat but as you no all the connections are in the ufh wiring centre

Speedfit jguh1 wiring centre thanks peter

you need to link a permanent live to "IN" and "out" connects to switch live in boiler. The boiler enable contacts in the wiring centre are connected to relay within wiring centre with volt-free contacts rated at 230V,3A maximum.

no the boiler requires L,N,E as well all taken from the load side of the same fused spur. The permanent live link to "in" just find a connection in the wiring centre you can come off.

FYI in is on the left and out on the right.

Sorry to be a dummy is this right ,the boiler has its independant supply ,then there is flex from the boiler with p/live a sw/l and a neutral
so from the ufh wiring centre connect one of the boiler enable to the live in the flex and the other boiler enable to the switch live in the flex ?
thanks peter

Boiler should have its independent supply, you shouldn't need another neutral for the switching from wiring centre.

I may have picked this up wrong though so probably best to ignore the post, Lee will clear it up lol.
