5.3.4 Thermal disinfection
After thermal disinfection the content in the hot water heater
slowly cools to the set hot water temperature. This mainly takes
place through heat loss. The hot water temperature can
therefore temporarily be higher than the set temperature.
Thermal disinfection guarantees a hygienic impeccable quality
of the hot water. The hot water is also regularly heated up to the
set temperature. This also contributes towards preventing
legionnaires' bacteria. This menu is used to configure thermal
disinfection.
