heat sources operate simultaneously in this mode.

3.

LEGIONELLA MODE

Thermal Disinfection involves increasing the temperature to a necessary disinfection temperature of at least 60°C in the entire
DHW circulation.
New regulations impose the obligation to adjust the tank to periodical thermal disinfection conducted at a water temperature no
lower than 60°C (recommended temperature 70°C). The ducts, fittings and technological system of hot water preparation need
to comply with this condition.
The boiler's disinfection is aimed to eliminate the Legionella Pneumophila bacteria which cause a reduction of the body's cell
immunity. The bacteria often multiply in stagnant hot water tanks (optimum temperature 35°C), which frequently happens, e.g.
in boilers.
After activating the Legionella Mode, the boiler heats up to 70°C (factory setting) and maintains this temperature for 30 minutes
(factory setting) and then comes back into regular operation mode.
From the moment the disinfection is switched on, the temperature of 70°C needs to be reached in no longer than 90 minutes
(factory setting). Otherwise, this function switches off automatically.
Any changes of settings for this function are only possible in the servicing mode.
