Swapping to dry contact from ebus receiver help

[BartmanUK]

The system (Glow worm Ultimate 30c) currently has a wireless receiver connected via eBUS.

In order to swap to a non eBUS receiver, where would you make the connection?

Currently as eBus is used, the 24v connections in the diagram are permanently joined together with a jumper wire and the receiver is connected to the two bus wires.

Here is a link to the full boiler manual - which has a few more pages about the wiring. http://www.glow-worm.co.uk/glow-worm/ultimate-c-157261.pdf

Can this boiler be activated via a dry contact receiver instead? Hoping you guys can assist.

Thank you

I'm presuming you would just connect the dry contact / low voltage to the 24v connections?

For example a Nest Heat Link, you would just connect its low voltage connections 2 and 3 to the 24v connections, and provide the heat link with power? Can any one confirm this? (So just four wires for Nest?
