7.8 Anti-legionnaire's disease protection (function activated only through the installer menu)

If activated, the water heater automatically carries out the anti-legionnaire's
disease protection function. The water is brought to a temperature of 65°C on a
monthly basis and for a maximum time of 15 minutes, so as to avoid germs from
developing in the water tank and piping (provided the water has not been
brought to T>57°C at least once for at least 15 minutes). The first heating cycle
is performed 3 days after the function has been activated. As these
temperatures may cause burns, it is advisable to use a thermostatic mixer.
During the cycle of antilegionella will be displayed "ANTI_B" alternately to the mode of operation, once the cycle is done
the set temperature remains the original one.
In the event that is enabled the two-tier rate signal HC-HP, the function will take place during the economic tariff. To
stop press "on/off".
