What should be the jumper position in the extension kit for the opentherm option? The power supply is given separately to the "L" & "N" contacts in the extension kit, the opentherm cables to "+" and "-". I am left only with the question of the jumper. Should it be position 1 or 2 like in the relay version?

    "The position of the jumper doesn't matter for Opentherm, you can leave it as it is."
