Boiler working overtime (vailant pump overrun)

[vaderag]

Photo of board attached. 24v loop is there

So just remove that?

Just looking at the instructions and it doesn't seem to suggest it needs removing unless you're using 24v controls... Am I misreading?

Jesus mate just remove the link, if it all goes t1ts up put the link back in, the fact you have a wire to the 240v rt means you cant have the 24v connection as well.

I'm not sure why it would be working at all if it were in place tho?

Mine was - when it shouldn’t have done. Just like yours. Just remove it.

Fair. It's out.
So far so good
Will watch it (well listen) over then next 24hrs and see if it's behaving properly!

Appreciate the help guys, fingers crossed!

So, seemingly completely coincidentally one of our taps just blew at the flex cable. And we have a very wet house.
I returned the jumper in a panic before finding the cause... It might be a while til I get round to removing it again!

The jumper has absolutely nothing to do with your taps, it is simply a signal link, your boiler thinks you want the heating on, the HW is completely seperate

Oh I know. There's no link whatsoever. Just bad timing!

Then take the link out before you damage the boiler.

You’re misreading. See edited photo, it states if using 230v controls, then remove link at x100, which evidently is the 24v link Also please ensure that since you have removed the case, which forms part of the room seal, that it isn’t checked in accordance with gas safety installation and use regulations 1998, after performing work on a gas appliance.

I thought I had, but it appears not. Try this one, although it’s not very clear by vaillant, it refers to that link.
