Operating elements and 
displays (Fig. E)

1 Temperature display LED (Stage I)

The LED indicates a temperature of approx. 35 °C when lit.

2 Temperature display LED

The LED indicates a temperature of approx. 45 °C when lit.

3 Temperature display LED (Stage e)

The LED indicates a temperature of approx. 55 °C when lit.

4 Temperature display LED

The LED indicates a temperature of approx. 65 °C when lit.

5 Temperature display LED (Stage III)

The LED indicates a temperature of approx. 75 °C when lit.

Note: Flashing of one of the individual LEDs 1–5 indicates 
heating in this temperature range.

6 Button 

The appliance can be switched between heating and frost 
protection mode with button 6.

In frost protection mode the appliance will automatically 
ensure that the water temperature is at approx. 10 °C, the 
tank is thus protected against frost. Only red LED 9 will light.

7 Selection

The required temperature can be displayed and increased 
with button 7.

8 Selection button -

Note “Heat once”: If buttons 7 and 8 are pressed 
simultaneously for approx. 3 seconds the tank will heat up 
once to the set temperature. This temperature can be 
changed with buttons 7 + and 8 – just for this “heat once” 
setting. Only orange LED 9 will light. After the set 
temperature is achieved the appliance will immediately 
reassume the previously set operating state.
The “heat once” function is possible in heating as well as 
frost protection mode.

Note: Cancel the “heat once” function by simultaneously 
pressing buttons 7 and 8 (return to previous operating state) 
or by pressing button 6 

 (frost protection mode).

9 Operational display

The LED lights red as long as the appliance is connected to 
the mains supply and indicates that the tank is operational.
The LED lights orange for the “heat once” function. 
The LED flashes red to indicate a malfunction.

■

Important: Flashing of one of the individual LEDs 1–5 in 
combination with the flashing red LED 9 of the operational 
display indicates the malfunction.

Operation

■

The appliance is switched over to heating operation with 
button 6.
LED 3 lights and thus indicates the preset temperature 
stage e (approx. 55 °C, factory setting). Heating 
commences after about 10 seconds, LED 3 goes off and 
the tank heats up to about 55 °C. 
During the heating up phase the LEDs flash consecutively 
and light up permanently in order to indicate the water 
temperature already achieved. The set temperature is 
achieved as soon as all LEDs light up.

■

Note: Only the set temperature will light if or – is 
pressed.

Display set temperature

Press button 7 or 8 once in order to display the set 
temperature. The set temperature is indicated by lighting of 
the corresponding LED.

Changing set temperature

■

Press button 7 + to increase the set temperature or button 
8 – to reduce it. The new set temperature is indicated by 
lighting of the corresponding LED. Heating commences 
after about 10 seconds without pressing the buttons

■

During the heating up phase the LEDs light up 
consecutively in order to indicate the water temperature 
already achieved. 

■

If the water temperature is higher than the newly set 
temperature, all the LEDs will switch off over time until the 
new water temperature is achieved. 

Example: Increase set temperature

The water temperature and the set temperature are approx. 
55 °C, the LEDs 1, 2 and 3 light up. The new desired 
temperature is approx. 75 °C.

■

Press button 7 + once, only LED 3 lights and indicates the 
temperature currently set.

■

Press button 7 + twice until LED 5 lights up.
The heating process will commence after approx. 10 
seconds, LED 5 switches off, LED 1, 2 and 3 will light 
again to indicate the temperature already achieved while 
LED 4 flashes to indicate that heating up continues. The 
set temperature is achieved as soon as all five LEDs light 
up.

Example Reduce set temperature

The water temperature and the set temperature are approx. 
75 °C, all five LEDs light up. The new desired temperature is 
approx. 45 °C.

■

Press button 8 – once, only LED 5 lights and indicates the 
temperature currently set.

■

Press button 8 – three times until LED 2 (approx. 45 °C) 
lights up.
The new value becomes effective after approx. 10 
seconds and heating is discontinued. The appliance cools 
down and the LEDs switch off over time until the set 
temperature is reached. LEDs 1 and 2 light up. 

Note: If the temperature drops, e.g. when water is used, the 
heating switches back on automatically. The LED flashes 
until the temperature is achieved.

Tip Water loss and scaling are at their lowest at water 
temperature setting stage e (approx. 55 °C, LED 3).
