Stat wiring advice on a Worcester?

[macka09]

Hi all. I’m fitting a Worcester 30si tomorrow and it’s having a Nest stat. I’m terrible with wiring so any advice you guys could give me would be great? Cheers

Wire it into the opentherm connectors mate. Also I have moved the to the GSR only section for you.

Worcester don’t have open

Easy Ls live out to nest live
Neutral to hive
Link L to 2
Then 3 to lr on boiler

My bad, thought they were. Can you tell I don’t fit them 😱😱

Seriously chaps. I know live neutral earth from fuse spur to boiler and that’s it. I’m trying to really break it down if I’m honest. I assume there’s an existing spur there so that’s my live to the boiler and then I’m stuck. Really does my head in.

Already told you how to do it 😀

Ls to live on the stat
Neutral from boiler
Link live to 2 on the stat
3 to Lr

Haha. Sorry mate.
So I’d need a five core flex coming from the boiler to the nest hub? What do I do with the 5th wire not used ?

tape up and leave i normally do or snip off

you could get away with a 3 core but its a bit tight

Do I not need an earth coming off the boiler to the hub? I’m even more confused now cos your telling me one way and a colleague saying another. He’s not taking anything from the LS port on the boiler

 

[ShaunCorbs]

no earth point and the case / touchable parts are plastic

hes going from the boiler live isnt he? problem is its hard to get two cores into one terminal upto you but i would use ls and lr

Ok so how am I taking a neutral from the boiler to the hub?

If I’m doing your head in mate just tell me to Sod off. I’ve asked a colleague to pop out and show me cos I’m sure it’s a piece of piddle after doing one. Typically I was told no

I’m here chaps ha. I managed to get it done thank you. Thanks for the advice. I was quite lucky really as the existing programmer had a 5 core going into the old boiler. So really all I had to do was link 2-live in the hub.

There’s a spare neutral next to ls in the Worcesters. Use this. 3 core is all you need with no earth. Literally 10 mins work
