The volume of water contained in the pipework between the circulation system and the tap which has the greatest distance to the system.
Remove the sediment from the storange water heater in accordance with the local conditions but at least once a year.
Thermal disinfection for 20 min at a temperature of 60°C, for 10 min at 65°C or for 5 min at 70°C at every draw-off point at least once a
week.
The water in the circulation loop shall be not less than 50°C.
No requirement.
If, for some reason, one of the aforementioned "Favourable conditions for the proliferation of Legionella " occurs, it is
strongly recommended that you enable this function by following the instructions listed in this manual [see section 7.11].
In any event, the thermal sanitisation cycle is not capable of completely destroying all Legionella bacteria in the storage
tank. For this reason, if the function is disabled, the Legionella bacteria could return.
Note: when the software performs the thermal sanitisation treatment, it is likely that the storage water heater will
consume more energy.
Warning: when the software has just completed the thermal disinfection treatment, the water temperature could cause
severe burns instantly. Children, the disabled and the elderly are at a higher risk of burns. Check the
temperature of the water before having a bath or a shower.
The default value is 60°C, which can be increased up to 75°C by means of the P23 parameter in the information menu
(see sect. 7.10)
