Intelligent thermostat compatible with Elm Leblanc Oxylis boilers
Does anyone know if the Elm Leblanc Oxylis boiler works with the Netatmo thermostat, I cannot get my thermostat working with my new boiler, it worked with my old boiler, I have wired it how Elm Leblanc recommend, live and neutral wires from thermostat to live and neutral connector in boiler, and grey and black wire to BUS connector in boiler, removing jump cable from thermostat connector, as Elm Leblanc recommend

Hm, without looking up this brand any closer I can say that connecting the black/grey wires to BUS is not correct. You have to connect them where the jumper cable was.
As the above person mentioned, I was following an Elm Leblanc Oxylis information video which was wrong, the Bus circuit (connector) only works with Elm Leblanc accessories, which Elm Leblanc have confirmed, the grey and black wires from the Netatmo must be connected to the blue thermostat circuit (connector) after removing the jumper wire, I did try this before and it did not work, maybe the wires have to be connected a certain way, ie this time the black is on the left and grey on the right, it is all working fine now,
Glad it‘s working now.
Polarity of the black/grey wires is not important, they never carry any currency. All that happens when the Thermostat switches on is that those two wires get bridged internally.
So usually there is a jumper cable somewhere that has to be removed and replaced by the black/grey wires. Then the boiler has to be adjusted (mode/temperature settings and so on) and then Thermostat will simply switch it on until the desired room-temperature is reached and then switches the boiler back off again.
