BDR91 to Hive Single Channel Wiring (Baxi Combi 24)

[Paul W Marshall]

Hi All

I have purchased a Hive thermostat/hub and am looking for a little advise.

Currently wired to a BDR91 as below on a Baxi Duo-Tec Combi 24.


I am ok with permanent live & neutral but just need advise on the other 2 wires.
The green/yellow wire in "B" has been wrapped with red tape.

Can anyone advise how to wire into the hive as below please?

Thanks in advance for any help.
Paul

A is your live (black wire) and b is your switch / call for heat (red tape)

 

[Leesparkykent]

I would replace the cable with a 5 core. Taping the green and yellow red and using it as a line conductor is just a bodge.

 

[Paul W Marshall]

A is your live (black wire) and b is your switch / call for heat (red tape)

Thanks for the reply. So which position would I put these on the hive ?

 

[Corbs]

Live and neutral as before

1 is a from old stat (back wire)

3 is b from old (red tape)

 

[Paul W Marshall]

Good stuff. Many thank for your help. I'll let you know how I get on.

Love the fact that the post about using an earth conductor as live switch wire is completely ignored because it was not wanted the OP wanted to hear!

Hi. Thanks for your input. Can you give details how to rewire with a 5 core cable on my boiler please ?

show me in the regs where it says you cant use an earth or a neutral colour core aslong as you mark it with the appropriate sleeve /colour

twin and earth its a no no

I’m afraid if you do not know you should be getting an electrician. Sorry to be so blunt, but electricity is dangerous and so many people that come on here asking for advice on how to install Hive or similar do not seem to realise this.

It's a bodge....it's the sort of carp plumbers pull

 

[Corbs]

so guess the regs agree with me only the same as sleeving each core of a control cable etc

if it bothers you that much sleeve the whole earth core so non is showing

I'm guessing you don't know then otherwise I'm sure you would be only to happy to help (said no one ever) this help forum is for help not negative comments from grumpy old men.

How can anyone give advice on how to do a job without seeing what is involved.
People come on here getting advice for free.
You have been told how you can make it work but myself and leesparkykent have both advised you that what you have is incorrect.
I then am on the receiving end of derogatory comments because you did not get what you wanted to hear.

There isn't a reg it's just highly frowned upon.

 

[Corbs]

so it fine then

I gave an IMAGE of my current wiring and asked for advice. I was advised accordingly by Corbs. You gave no positive input whatsoever. Why are you even on this forum ?

 

[Leesparkykent]

Yeah if you like doing highly frowned upon work.

I often find there are two types of electrician, skilled and those who tape up a green/yellow conductor for another purpose.

 

[Corbs]

Yeah if you like doing highly frowned upon work.

how, so your telling me you would go to change a stat and see someones used a a core you dont like using (lets say a 6360) and theyve used the flexi earth all labled up as a core (both ends)

you would say no i cant install your new stat and i need to rip apart your house to install a new cable

hows it any different than using the neutral core as a call all correctly labelled etc , its not

so you would re purpose a neutral core

WOW

Where did I tell you that?

Define a neutral core.

 

[Corbs]

Where did I tell you that?

"Yeah if you like doing highly frowned upon work." and some one of your calibre wouldnt do frowned upon work

 

[Corbs]

Define a neutral core.

can be any core if labelled correctly (cant be the earth in twin and earth)

I don't recall saying anything about ripping apart someone's house? Would you mind telling me where I did? A skilled tradesman shouldn't be ripping houses apart....The OP has a hive, the hive receiver can be wired into the boiler which wouldn't mean "ripping the house apart" If you have to rip a house apart to install a thermostat then maybe you should look at choosing another profession?

 

[Leesparkykent]

That isn't the definition of a neutral conductor....why are you trying to skirt around the correct answer/definition?

post 18 tell me what would you do then if you had nothing else but the earth core / spare core off a flex

completes the circuit and carry s a negative current away the same amount that is being drawn from the live within a tolerance i believe

I would explain to the customer that the plumber who installed it had done it in such a manner that is highly frowned upon but actual electricians. I would then say that you now have a few options we either install a wireless thermostat, install a new cable or purchase a thermostat that only needs a two wire connection rather than three.

So is it a live conductor?

what happens when the customer says what regs have they broken by doing such bad practice wiring

no but who defines what each core is used for if acceptable and ok in the regs the qualified person installing it

I didn't say they had broken regulations I said it was regarded as frowned upon by any electrician who's worth Their salt.

right ok

will write bs and iet a strongly worded letter saying they must make it a reg and mandatory to everyone

All up and running. Many thanks to Corbs for your help. And thanks to the others for keeping me entertained for the evening
