Boiler not firing up sometimes

[Gasmk1]

he has a hive for controlling the system so something is wrong either with the wiring or the hive programming

But, if you do not feel confident enough then I would suggest get a professional electrician out.

I am happy enough do do it but I always like to check with the experts

You don't need to cut link 6. The pump live is wired direct to the boiler as the PCB in the boiler controls the overrun on that boiler.
It will be a control issue. You just need someone to spend a little time going over the wiring to check the controls.

Is that the correct way to not use the terminals and connect the pump l to boiler p/l ? I am just wondering if you cannot use the terminals and cut link 6

Well I connected the wires as we said and cut the link 6 and it all seems to work ok including the pump overrun.

Now I have to see if that has cured the origional problem

It will work that way, but the boiler is now not installed to manufacturer's instructions so you could risk voiding the warranty. The pump should be wired directly to the boiler.

So does that mean that if you have a Honeywell Junction Box you cannot use it to connect the pump to the boiler.

Does that apply to using any junction box or does the pump have to be wired directly to the boiler

How does the Honeywell JB link 6 affect how the overrun work

The boiler isn't controlling the pump

No just don't wire the pump live to the controller,

I'm sorry to say get a heating engy in to test things before you start ripping things out and re wiring them, when the problem might not be with that

Thanks for all your help with this.

Now put back to the old wiring.

Are there any recommended heating engineers in the Middlesbrough area, as so far i am not very impressed with the ones that have been round.
