Would you please help with the correct wiring of Netatmo Thermostat Relay in Protherm Gepard boiler?
I understand grey and black wires should probably go to the terminals marked „RT“ and „24V“ after removing the shunt, is that correct?
Also I probably need to connect the brown (L) and blue (N) wires to the boiler‘s power source, but the terminals are already occupied with another pair of cables. Shall I replace it? Or can I alternatively plug the cables to mains adapter and plug it to power socket?
Many thanks for your help!

Re: Correct wiring to Protherm Gepard boiler
Black and Grey to RT24V is correct.
If this is the main connector of your boiler, replacing those wires will disconnect it from the grid.
You can either split the installed power supply wires to add the Netatmo Relais blue and brown wires with terminals or you go the way with the plug, which is probably the better solution if you‘re not experienced with electrical wiring.
But judging from that second photo, it should be possible to add the Relais‘ wires by opening up the screws all the way with the power switched off before, of course.

Re: Correct wiring to Protherm Gepard boiler
Thank you for your reply. There is no downside of connecting the relay straight to the power via plug I assume? And do you please just attach the plug to the back of Relay? I am still waiting for mine to arrive so not sure how that works. Cheers!

There is no downside, no.
In fact, it is necessary if you want to power the Relais through an outlet but want to control the boiler with the Relais as well. The provided plug-adapter can only be installed instead of the boiler cable, meaning you loose the option to control the boiler with the Relais and you need to wire the Thermostat instead.

Just came back to thank you GEORGzer, I did the wiring based on your suggestions and it works just perfectly.
