3. Appliance description
The appliance electrically heats up domestic hot water with the
standard heating output or with rapid heating. The electronic
control unit makes energy saving adjustments easier. Subject to
the power supply and draw-off behaviour, the water is heated
automatically to the set temperature.
The digital display provides you with information about the se-
lected set temperature and the enabled functions.
The inner cylinder is protected against corrosion by an enamel
coating in conjunction with the integral protective magnesium
anode.
The expansion water that collects as the water is heated up is
drained off via the safety valve.
The thermal insulation is made of environmentally friendly and
recyclable polyurethane foam.
The water heater is protected against frost, but the safety valve
and water lines in the apartment or house are not. If the appliance
is disconnected from the power supply, the water heater is not
protected against frost. In such cases, if there is a risk of frost, the
water heater must be drained.
The appliance can be operated in three ways: as a single circuit,
dual circuit or manually.
Single circuit operation
In this operating mode, the appliance heats up the water automati-
cally with the standard heating output at any temperature setting.
You can also start rapid heating.
Dual circuit operation
During off-peak tariff periods (cheap rate periods of power supply
utilities), the appliance automatically heats up the water heater
content with the standard heating output at any temperature set-
ting. You can also start rapid heating.
Manual operation
The appliance only heats the water when the rapid heating button
is pressed. Once the maximum possible temperature has been
reached, the appliance switches off and does not restart auto-
matically.

During operation, the symbols for all enabled functions are il-
luminated.
When setting the menu functions, only the symbol for the current
function and, if required, the heat-up symbol are displayed. The
current setting of the function is displayed.
To save energy, the luminous intensity is reduced if you do not
make any settings for approx. 5 minutes. As soon as you press a
button, the display and symbols are illuminated again.
