Hive install to Vokera vision plus 40c

[ZiberU]

I’d like to install a hive i have purchased connecting to my boiler. I have a hive mini and vokera vision plus 40c.
I can pick up the live and neutral but don’t know where to connect the hive to the boiler (see picture)
Any help would be appreciated. Thanks

Remove link inside the boiler at CN5 and use this - it’s volt free so no mains links!

if I’m reading this correctly the terminals coming from the hive are volt free?
Eg l and n are 230v into hive and the others 1,2,3,4 are not (which is where i should be connecting cn5)

Yes, exactly this

...yes, CN5 to terminals 1 and 3 of the (Single Channel) Hive mini receiver.

I would look for manual then do a "Find in page" hunt for Opentherm, if you get a hit then Hive is not a suitable thermostat. However there may be a default option where the boiler replaces a previous one, so thermostat is next word, and see if it says some thing like 24 VDC is so then must use a volt free thermostat, the Hive single channel is volt free.

There is a diagram there is a good diagram which does show what is what. however the instructions are rather involved.

Personally I would not attempt to fit a thermostat myself, swap one already fitted yes, but a quick read of the manual and look at your picture I see no link here

so it seems likely some changes as to how boiler is configured may be required, I have no intension of reading the manual for you.

Then look harder!
The small black tab in the picture, is the edge of the bridge, linking the terminal blocks.
No changes to the configuration are necessary.

The Vokera is ELV switching - hence...

it’s volt free so no mains links!
