Central heating pump on continuous

[tony clark]

should have been easy if i remember rightly the suprima had a switch live a neutral and pump live
not much different from bosch any heating engineer worth his salt should be able to do this blindfolded

The installer was not correctly qualified/competent, you should get them back to move the doubled live to x14 to ensure you are covered by their insurance.

Should be a 4C flex into the boiler and a 3C out of it to the pump from X14. As it is, it looks like the neutral to the pump could be disconnected during maintenance, leaving a live connected to it, which could be dangerous.

Brian, I think you're missing the fact the flexes obviously go back to a joint box of some sort as the boiler call signal and pump live are in the same flex.

Timbo you are correct in the joint box( wiring centre) and the neutral and linked live feed will go to pump from there, but there really needs to be more conductirs in that boiler.

the pump terminations require live neutral and earth.
Just popping the pumps live Feed in the Termination strip Isn’t good enough.
All 3 terminations need filling. You can then take the fed direct to the pump or back via the wiring centre.

it may be that a link has been taken between both neutral and earth terminals, this if fine but I frown on it.

I know it would work functionally, but if your going to do a job do it right.
