12.9 Selecting and setting up thermal disinfection
If you select the "Therm. disinfect" function, the DHW is brought to a temperature
(70 °C) once or several times a week. This is high enough to kill off germs
(e.g.
legionella bacteria).
The cylinder primary pump and DHW circulation pump run constantly during the
thermal disinfection process.
If you have selected "Therm. disinfect yes", thermal disinfection commences
according to factory settings or your own preferences.
Thermal disinfection is indicated by LED on the FM441 module.
You may adjust the factory settings for thermal disinfection via additional menus.
The system tries to reach the set thermal disinfection temperature for three
hours. If
this fails, the fault message "Therm. disinfect failed" appears.
You may also set up thermal disinfection via your own switching program.
