E.l.m leblanc megalis ngla24 24-4h / thermostat installation

Post by nkrs »

Hi, I am trying to install the netatmo thermostat in my e.l.m leblanc Groupe Bosch gas heater.

There are already 2 cables connected to L&N, whicu is the power outlet. I tried disconnecting them and connecting the ones from the thermostat - doesn't work.

Should they be all connected in the same place or in outlets 1 2 of the 1234 one?

I attach the picture of the heater and its instructions.

Thanks!!

Add the Netatmo Relais‘ brown and blue wires to L and N.
Connect the black and grey wires to LS and LR, polarity not important.

No, as said add the new ones, don‘t replace them.
