The Manual for the HRE Intergas boilers says:
8.3.2 On / off room thermostat (low voltage)
To be connected to contacts 6 and 7 of connector X4.
This is a 24 volt connection and no mains power must be applied to these terminals. See chapter 13, electrical diagram.

When a 24 volt thermostat is connected to contacts 6 and 7, the loop in 6 – 7 must be removed
5. The on/off room thermostat has to be connected to the contacts 6 and 7 of connector X4.

So there must be a bridge cable between connector 6 and 7 if no other thermostat is installed.
Remove the bridge and connect the Netatmo Relais' black and grey wires to those contacts (polarity doesn't matter).
Then you have to add the Relais' brown and blue wires to a power source. In this case the main supply should be connected to the contacts 2 and 4 of the X2 terminal.

I suppose it should be 11 an 12, those are the open therm pins.

@jgeers01

For an OpenTherm Thermostat, yes.

But OP never stated what Thermostat is going to be installed and since this question got postet in the „analog smart Thermostat“ section, I went with that 😋
