Electromechanical water heaters are sold with the thermal sanitisation cycle disabled (default setting). If, for
some reason, any of the above ‘’Conditions in favour of the proliferation of Legionella’’ occurs, it is strongly re-
commended to enable this function according to the instructions found in this manual [see <<
Activating the
‘’thermal disinfection cycle’’ (anti-legionella)
>>]. However, the thermal disinfection cycle does not kill all
Legionella bacteria in the storage tank. It follows that if the function is disabled, the Legionella bacteria may
reoccur.
Note: when the software performs the thermal sanitisation treatment, it is likely that the power consumption of
the water heaters increases.
Caution:
the water temperature in the tank can cause immediate serious burns when the software runs the
thermal disinfection treatment. Children, disabled persons and the aged are particularly at risk of
burns. Check the water temperature before taking a bath or shower.
