3. Appliance description
The appliance electrically heats domestic hot water, with the tem-
perature controlled via the temperature selector. Subject to the
power supply and operating mode, the water is heated automat-
ically to the required temperature. You can use the appliance to
supply one or several draw-off points.
The steel cylinder is coated on the inside with special directly ap-
plied enamel and is equipped with a thermometer and a protective
anode. The anode with consumption indicator protects the cylin-
der interior from corrosion. The cylinder is enclosed by thermal
insulation and a casing.
The appliance is also protected against frost on the temperature
setting "cold" as long as the power supply is guaranteed. The ap-
pliance switches on in good time and heats the water. The water
supply line and the safety assembly are not protected against frost
by the appliance.
Single circuit operation
The appliance automatically heats up at any temperature setting
subject to the availability of power.
Dual circuit operation
During off-peak tariff periods (cheap rate periods of power supply
utilities), the appliance automatically heats up the water content
with standard heating output at any temperature settings. In ad-
dition, you can switch on rapid heating during peak tariff periods.
4. Settings
The temperature is infinitely adjustable. Depending upon the sys-
tem, the temperatures may vary from the set value.

limitation can be cancelled by a qualified contractor (see chapter
"Installation / Settings").
Dual circuit operation with rapid heat-up function
You can switch on rapid heating with the pushbutton whenever
necessary. Rapid heating stops and will not restart once the se-
lected temperature has been reached.
