Siemens RWB7 to Hive

[deadlock]

Hi, long time lurker but first-time posting!

I currently have an old Siemens RWB7 (with no thermostat) that I was thinking of replacing with a Hive Thermostat. It's wired, per the attached photo, to a Vokera Vision 25S standard boiler.

From what I can glean from here and elsewhere, I should be able to re-use the current backplate. The N and L wires are already connected to the right terminals, and I need to move the wire from terminal 4 to 3.

I'm unsure what I should do with the link from L to 2 - should I move that to terminal 1?

Looking more closely at the photo, it looks like there's a second wire connected to terminal 4 - should I move that to 3 as well?

Thanks for any help!

Yes move the linked terminals in 2 to 1 and move 4 to 3. Industry standard backplate should take the Hive.

Thanks - so I connect L to terminal 1 as well?

Also, since this is a standard boiler and doesn’t heat water separately, I need the single channel receiver, right?

Yes, as it’s currently linked.

yes, as the Siemens is a single channel
