 SAFETY
2.1 Intended use
The appliance is intended for heating domestic hot water and can supply one or more draw-off points.
This appliance is designed for domestic use. It can be used safely by untrained persons. The appliance can
also be used in a non-domestic environment, e.g. in a small business, as long as it is used in the same way.
Any other use beyond that described shall be deemed inappropriate. It is not permissible to heat other
liquids or materials. Observation of these instructions and of instructions for any accessories used is also
part of the correct use of this appliance.

!WARNING Injury
The appliance may be used by children aged 8 and up and persons with reduced physical,
sensory or mental capabilities or a lack of experience provided that they are supervised
or they have been instructed on how to use the appliance safely and have understood the
resulting risks. Children must never play with the appliance. Children must never clean
the appliance or perform user maintenance unless they are supervised.
!Damage to the appliance and environment
Protect the water lines and the safety assembly against frost.
Note The appliance is under pressure. During the heat-up process, expansion water will drip
from the safety valve. If water continues to drip when the heat-up process is completed,
and if the water pressure is lower than 0.6 MPa, please inform your heating contractor.
2.3 CE designation
The CE designation shows that the appliance meets all essential requirements according to the:
-Electromagnetic Compatibility Directive
-Low Voltage Directive
2.4 Test symbols
See type plate on the appliance.
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 selected set temperature and the enabled
functions.
The current temperature standard value is provided by the analogue temperature indicator.
The inner cylinder is protected against corrosion by an enamel coating in conjunction with the integral
protective magnesium anode.

10
OPERATION GB
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 automatically 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 setting. 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 automatically.

your draw-off behaviour.
When you select ECO Dynamic mode, the appliance evaluates your draw-off times and quantities for a
week. The next week, you have the required mixed water volume available at the draw-off time. The ap-
pliance monitors your user behaviour and automatically adjusts the heat-up times as required.
This energy saving mode is optimal if you require hot water at the same time during a week. If your draw-
off times change, hot water is available the next week at the new times.

4.4.4 Commercial mode
The heating contractor can adjust the appliance for commercial applications, e.g. in doctors’ practices or
butchers (see chapter "Installation/settings"). The set temperature is then adjusted manually. The energy
saving mode button is not enabled in commercial mode.
4.4.5 Adjusted use of off-peak tariff periods
(reverse control with dual circuit operation)
This function is not enabled in the factory settings. The heating contractor can enable reverse control of
the appliance.
This means that the appliance evaluates the cheap rate periods of your power supply utility for 7 days to
make the most of off-peak times. The aim is to start heat-up at the right time so that the full water heater
content heated to the set temperature is only available to you at the end of the off-peak time (optimum
standby energy consumption).
4.4.6 Switching rapid heating on/off
With rapid heating, the appliance heats the water content up to maximum temperature. If you have switched
on a temperature limit, the selected temperature limit is also the maximum value for the set temperature.
Once the maximum temperature has been reached, the rapid heating function is switched off automati-
cally. In standard mode, the previously selected set temperature is enabled again.

6 TROUBLESHOOTING
Problem Cause »Remedy
The water does not heat up and the
display does not light up. There is no power. Check the fuse/MCB in your fuse box/distribution panel.
The water does not heat up sufficient-
ly and the heat-up symbol lights up. The set temperature is set too low. Select a higher set temperature.
The appliance heats, for example,
after large amounts of DHW have been
drawn.
Wait until the heat-up symbol goes out
again.
The outlet flow rate is low. The aerator in the tap or shower head
is scaled up or contaminated. Clean and/or descale the aerator or shower head.
The appliance does not respond
when a button is pressed.
The key lock symbol is flashing.
Key lock is enabled. Disable key lock (see chapter "Set-
tings / Menu functions / Enabling/
disabling key lock").
The display flashes. Notify your local contractor. Display
the fault code (see chapter "Settings /
Menu functions / Displaying the fault
code").
If you cannot remedy the fault, notify your heating contractor. To facilitate and speed up your enquiry,
please provide the serial number from the type plate (000000 and 0000-000000):
