Hive to Potterton 28 wiring

Hello,
Can you please advise me if my wiring diagram looks correctly? I've ordered few days ago Hive without installation and from what I've gathered that seems how it should be looking like, but I would ideally need confirmation from somebody that knows better then my very amateurish skills.

That's from electric schema on the boiler and how it looks inside:




My current external thermostat that's probably hooked up to 1 & 2 on terminal block(?):


Front of the boiler(just in case):


And finally schema I came with:


I'm not sure if I should hard wire Common and Heating off on Hive(the lime connection)?
And I presume I should disconnect 1&2 from terminal block that would be my current external thermostat? Should I wire Earth to Hive as well?
Does that look ok?

Thanks in advance for all replies.

 

No you have got it wrong you need a live and neutral to the hive receiver and the two wires in your existing thermostat go to 1 and 3 on the hive, doesnt matter which way round, no earth needed and dont make any links

 

So that would make it look more like it?


Live & Neutral coming from external source? No earth, no links.
Do I take off the current cables from left of the terminal block(1&2) that I presume is that external thermostat(boiler is in the kitchan and thermostat is couple meters away and wiring goes not a clue where in the walls) which is not going to be used anymore?

 

You don’t need the lime link wire, everything appears ok, you can piggyback the Live and Neutral from boiler, and 230v to common and switch live back (dark green and yellow) respectively on original schematic.

 

Cool. That's what I was hoping for. Will not put lime link wire in. And piggybacking Live & Neutral from boiler seems like an easy-win.
Two questions over here though.
1) ianmcd says that's wrong, like I've mentioned I'm amateurish so I was wondering why was that?
2) I presume that I take off the current cables from left of the terminal block(1&2) that I think go to current thermostat?

 

What you are fitting is a simple switch, the receiver needs a supply to power it, the switching part is simply on/ off nothing complicated

 

Ah. Sorry I thought that by saying it's wrong you've said it's all wrong, my mistake.
I will then patiently wait till it arrive and hook it up like on 1st diagram, minus the lime link.

Do I remove those additional cables 1&2 from terminal block?

 

you need L&N to power the unit and it is switched between 1 & 3 simple as that , it is not rocket science, it is a very smart switch but that is down to the unit not you

 

Yeah but I can hook it up to the L&N from the boiler right(as on the schema)? That's what I was hoping and seems like @Chris_W confirmed.

 

Just dropping off final cleaned schema that I'm going to go with for the people that will be potentially looking at this thread. Thanks for all your help.
