Tado - Bosch olio condens 3000f

Hi all
I have a Bosch Olio Condens 3000 boiler.
I have just purchased a Tado v3+ to replace my existing netemamo thermostat.
I am having trouble with the receiver part that is wired into the boiler.
I have watched YouTube videos on the installation and it suggests that I wire the receiver into the boiler via the 230v live and neutral, however, on my receiver I have a European plug on it with no option to wire straight to the boiler 230v. (I do live in France)
Do I plug the receiver in separately to the boiler?
Then I’m not sure where the link wires (I have 3 that come with the set up) go
I’m pretty sure that it’s the 230v relay SL and L to Com and No but I have no SL or NO on the back of my boiler.
The original Netamano was wired into a symbol of a house
Any advice would be appreciated.
