Further on we learn, in english:

"The machine is fitted with a two-position power switch:
Position OFF: no power supply to the internal components.
Position ON: power supply to the operational electric components (boiler filling with water).
• Boiler heating element ON/OFF switch:
Position OFF: no power supply to the boiler heating element
Position ON: power supply to the boiler heating element"

Implication being you can cut the heating element off to, one presumes, manually modulate water temp. That seems interesting. My presumption may be wrong but, if the temp gauge is precise, you could moderate the temp of what you pump if the thermostat gives you more heat than you want.

Maybe.
