7.9 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.
The achievement of temperatures above the set is marked with the symbol of the waves.
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".

7.11 Operation with two-tier electricity rate
To be able to operate also on appliances with a two-tier rate system, the control logic calculates the number of
average hours a day during which the power supply is available in the economy mode (HC).
A self-learning function ensures that the appliance reaches the pre-set temperature in the time range during which the
economy rate applies; the maximum limit of hours is determined by the P9 TIME_W parameter; after the initial start-up
(or after switching off the hardware), the default setting is 8 hours.
