2 Function
2.1 Steam System
The appliance has two heating systems. This allows for independent preparation of
froth/cappuccino or espresso/coffee. The second heating system can be turned off to
save energy during the heating phase, e.g., if froth is not prepared very often. When
the steam system is turned off and froth or cappuccino is selected, the appliance must
heat up first to produce steam. The steam system is turned on by default.
