HIVE help

I have just purchased a HIVE active heating. My boiler is a basi M90e
https://www.biasi.co.uk/assets/public/installer_literature/34/Riva Compact_Service Manual.pdf

I think I have a thermostat currently it’s always set to maximum I don’t really use it. I took the cover off and there’s a red black and earth wire. I have old wiring so I assume live neural earth. No idea if this thermo is even in use. How would it connect to the boiler if so?

Heres the wiring set up on the boiler

02821-AAA-026-E-4-C77-AF45-5-A66-FCC43-C8-D - 02821-AAA-026-E-4-C77-AF45-5-A66-FCC43-C8-D

the hive set up

06388BFE 09B0 4376 A46B 0E369D87A60E - 06388BFE 09B0 4376 A46B 0E369D87A60E

I know it’s the bottom block I need to change. Please could someone explain which wires I put into which bits on the HIVE. Also do I remove that black linking wire? What should I fit to the earth tether. Do I need to set the boiler current clock to always on? I assume I remove the live and neutral wires from the top connector box and put these into my hive L and N. Then the bottom block blue I think is my CH on as it links with the red terminal wire which I think is maybe my thermo. So CH on blue, CH off grey take these out and out them into the hiv correct on/off ports. Now it’s just the red wire I am unsure about.

Thanks

If you don't know, don't rely on a random internet forum, get a professional in.

The odds of you being able to do anything dangerous by wiring it wrong, beyond blowing some circuit boards, are slim, but do you really want to just take the advice of a complete stranger who may have no idea what they're talking about and is basing their advice on a single picture, that if done wrong may do anything from nothing to rendering your boiler needing repairs, or killing your hive thermostat, I say this as a serial mis-wirer in my early days, the amount of expensive tech that ended up in the bin was embarrassing.

If you don't know, and you're not confidence, spend the £100/£150 and get the peace of mind of a gas safe installer to fit it, look over his shoulder, see what he does and then you'll know next time if you decide to move away from hive.

Wire L, N and E from hive backplate into top block and wire 1 & 3 from hive into where the black link is on the bottom block.

Doesn’t look like your current stat is wired in.

Make a note of what you take out and where it went and always work safe.

Thanks. Yeah think remove link. I don’t think the old thermo is in the loop as the black link wouldn’t be present. I think my grey and blue at bottom are choff and on? The manual says external controls go into 1-3 so maybe you’re right I’ll try both. There was another thread from a while ago and someone said they did middle and end.
is a 5 core ok to use?

Yeah looks ok to me.

Once you’ve wired in LN&E you’ll only have two wires left which then go into where that link is and then into 1&3 at hive backplate.
Should be quite straightforward.
