Temperature adjustment
Use the
key to set the desired temperature (factory setting is 55 °C). Water temperature can be set in the range from 10 °C to
75 °C with 5 °C increments. When the maximum level of 75 °C is reached, the next time you press the
the minimum level of 10 °C. We recommend the "eco" setting. With this setting, water temperature will be at approximately 55 °C, and
formation of limescale deposits and heat losses will be lower than at higher temperature settings. When you last press the
setting is stored. After a while (approx. 5 seconds), the current temperature in the hot water storage tank is displayed on the display
unit
.
If the appliance is disconnected from the power mains and there is a danger of freezing, then water has to be drained from the hot
water storage tank.
The table below shows the LED lighting for respective temperature levels.

Power supply failure protection
In case of power supply failure, the settings remain permanently stored.
After restart, the appliance operates in the same regime as before the power supply failure.
Activation of the "TURBO" mode
This operating mode is suitable especially when you need a large amount of hot water quickly. In the "TURBO" mode, the water in the
hot water storage tank is heated with the heat pump and the electric heater simultaneously. This means faster heating of water to the
set temperature.
You can choose between one-off and continuous activation of the "TURBO" function.
For one-off activation, briefly press the
in the hot water storage tank is heated to the set temperature. When the temperature is reached, the function is switched off
automatically and the indicator
For constant activation, press and hold (3 seconds) the key
that is lit. When the temperature is reached, the function is not switched off automatically. To deactivate the function, briefly press
the
key, and the indicator
During operation of the "TURBO" function, the user can set the temperature, deactivate the function, and switch off the appliance.
Anti-Legionella program
If the water in the hot water storage tank is below 65 °C for 14 days, the anti-Legionella program is activated to heat the water in the
hot water storage tank to a temperature of 70 °C. During the anti-Legionella program operation, respective segments will be
consecutively lit on the display unit
is not possible; however, the "TURBO" function can be activated and deactivated.
If the appliance is switched off or there is a power supply failure while the anti-Legionella program is in progress, the anti-Legionella
program will resume when the appliance is switched back on or power supply to the appliance is restored.
Fig. 9: Indication of the anti-Legionella program
Warning: after heating up in the anti-Legionella program, the temperature of the water in the tank is 65 °C or more, regardless
of the temperature set for the appliance.
