hive heating won't turn off baxi 105e HELP!!

[JohnW2]

No , old thermostat and programmer was removed during renovation works. Boiler has been without a thermostat for months.

How did you get the boiler to work with the thermostat removed? It sounds as if someone must have put a link in somewhere (so that the boiler was permanently 'on').

Kind Regards, John

Thermostat was removed and only way to control the boiler was to manually select heating and hot water . There was no temperature control just all or nothing

I wasn't suggesting that there would be any temperature control without a thermostat. However, when one removes a thermostat it would (at least in my experience) normally/commonly be the case that one would have to insert a link (to emulate the thermostat) for the boiler to work at all. Do you know what was none with/to the cable that was connected to the thermostat before it was removed? Is it (the cable) still in place, or was that also removed?

Kind Regards, John

 

[Ben1888]

Everything was removed there is nothing connected to the boiler apart from hive . I will take some pictures tomorrow and hopefully someone can help. Thanks again

Hive wiring

Ok here is the wiring to my baxi 105e from hive receiver. Anyone any ideas now?

I noticed there are 2 black wires coming out of 1 in the boiler is this correct ?

 

[Ben1888]

No. No links.

Something wrong somewhere.

Remove the wire from 3 on the receiver. Does boiler go off then?
If it does then there must be a problem with the Hive.

Removed wire from 3 on receiver and boiler still firing ? So looks like no problem with hive?

 

[Ben1888]

And here is the wiring to my receiver please someone help this is driving me
Nuts!!

Regarding the boiler wiring. There are two black wires in the terminal one up from the bottom (1). That's wrong. One of them should be in the bottom terminal (2) It doesn't matter which one.

As per the diagram posted by EFLimpudence earlier.



EDIT
In the photo of the Hive backplate wiring it looks like the earth is coming out of the brown wire, and they say the camera never lies.

Ok I will go and try that thanks for the quick reply

Haha bad photography ! The earth was not coming out the brown wire lol.

So I put one of the black wires into 2 and it's worked! So pleased thank you so much don't know why there were 2 blacks coming out of 1 but moving it has sorted the problem. Thanks to all who contributed

Good, glad it's working. EFLImpudence and JohnW2 had already worked out the problem.

No other wires in 1 or 2 in the boiler?

However, when one removes a thermostat it would (at least in my experience) normally/commonly be the case that one would have to insert a link (to emulate the thermostat) for the boiler to work at all.

Instead of the installer inserting a link between terminals 1 & 2, the boiler black wires had simply been put in the same terminal instead, which from an electrical point of view achieves exactly the same thing. Your photo of the boiler wiring just served to highlight where the problem actually was.

Deffo something not right going on there.

So where is it from?

And what's with that cut in the insulation?

Yep, that counts as a 'link' to me (functionally), even though it obviously would not have been apparent as such to the OP

Glad you managed to get it sorted out for him!

Kind Regards, John
