the extra DHW function is activated.

5.3.4 Thermal disinfection
Following thermal disinfection, the cylinder content slowly
cools back down to the set DHW temperature. The cool down is
effectuated mainly through heat losses. Consequently, the
DHW temperature may briefly be higher than the selected
temperature.
The thermal disinfection safeguards the hygienic quality of the
DHW. The hot water is heated regularly to the set temperature.
This also kills off legionella, for example. Thermal disinfection
can be configured in this menu.
