Boiler system
Turn on the device using the ON/OFF switch. The display will light up. If the boiler [1] is empty (at the
first installation or after running the shut down menu), the commissioning menu will automatically start
and will guide you through the filling-up sequence. If the boiler is filled, the heating element [1.3] will
be switched on by the power relay [3]. As soon as the NTC sensor [1.1] measures the set temperature,
the heating element [1.3] will be switched off. The insulation [1.5] prevents the boiler from cooling
down. The boiler is tested at an overpressure of 13 bar (1.3 MPa) constructed for working pressures of
10 bar (1.0 MPa).
