Since "–" is the lowest mode of use, the tank ensure the best energy efficiency in
this setting. Compared to the maximum temperature setting, scaling and

If you rotate the knob after the "++" setting, you can continuously adjust the
temperature of water in the tank between 60 and 75 °C.
If you choose this setting, the product will function as a conventional water

setting will keep the water temperature at the selected value.
In this setting, the benefits offered by the self-learning function are not available,
thus we recommend this setting on a temporary basis only!
