    Hello! What connection scheme is used: single-phase or three-phase? We can’t send the electric circuit of the boiler, because it simply could not be found either on the official website or on independent sources. But you can use the standard scheme for connecting an electric boiler with three heating elements. The phase from the thermostat goes to the starter coil, and zero is taken directly from the mains. Three phases from the machines enter the contactor and from it go to the electric heating elements.
