2.  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 inappropri-

ate. It is not permissible to heat other liquids or materials. Obser-

vation of these instructions and of instructions for any accessories 

used is also part of the correct use of this appliance.

2.2  safety instructions

DANGER Scalding

During operation, the tap and safety assembly can reach 

temperatures in excess of 60 °C.

There is a risk of scalding at outlet temperatures in ex-

cess of 43 °C.

!

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 result-

ing 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

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.

Use the plus and minus buttons to 

adjust the set temperature from 20 to 

85 °C or select the frost protection set-

ting at 7 °C.

As soon as the water temperature drops 

below the selected value, the heating ele-

ment automatically switches on. The heat-

up symbol is displayed until the tempera-

ture reaches the selected set temperature 

again.

When 7 °C is selected, frost protection is 

switched on automatically and the frost 

protection symbol appears.

Note

If you change the set temperature, the appliance switches 

automatically to ECO Comfort energy saving mode.

For low water consumption or very hard water, we recommend 

a low set temperature, as water above approx. 55 °C deposits 

limescale.

If the appliance is not in use for long periods, select 7 °C as 

the set temperature (frost protection) or disconnect the appli-

ance from the power supply in order to save energy.

For reasons of hygiene, heat up the content of the water 

heater once to above 60 °C before initial use.

4.3.2  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 automatically. 

In standard mode, the previously selected set temperature is ena-

bled again.

If there is a fault and the display flashes, the 

fault code (see chapter "Troubleshooting") 

is displayed. 

4.4.3  selecting energy saving mode

eco comfort (factory setting)

This energy saving mode always offers you the maximum amount 

of hot water and therefore maximum comfort.

In ECO Comfort energy saving mode, the set temperature is auto-

matically reduced after a week from 85 °C to 60 °C.

In ECO Comfort energy saving mode, you can also adjust the set 

temperature manually at any time between 61 °C and 70 °C. This 

is also possible immediately after commissioning and after au-

tomatic reduction of the set temperature. If you select a set tem-

perature higher than 70 °C, the set temperature is automatically 

reduced again after a week to 60 °C.

eco Plus (with single circuit operation)

This energy saving mode offers you the advantage of energy sav-

ings, as heating is only carried out after considerable draw-off.

In ECO Plus mode, the appliance heats up automatically to the set 

temperature of 60 °C once you have drawn off 40% of the water 

heater content.

eco dynamic (with single circuit operation)

This energy saving mode offers you maximum energy efficiency 

through intelligent dynamic matching to 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 appliance 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.

The set temperature is set immediately to 60 °C.

Note

In commercial mode (see chapter "Commercial mode") 

and in manual operating mode (see chapter "Appliance 

description"), the ECO menu functions are skipped.

functions are then skipped.

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 com-

mercial 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  setting the temperature limit

Note

If you switch on the temperature limit in ECO Plus or 

ECO Dynamic energy saving mode, the appliance switches 

automatically to the ECO Comfort energy saving mode.

You can limit the set temperature to between 40 and 60 °C or
