P2 parameter – Anti legionnaire’s disease protection
If enabled, the water heater automatically performs the anti-Legionella protection
function. The water temperature must remain higher or equal to 55°C all day or higher
or equal to 60°C for at least 1 hour. These temperatures can cause burns, so we
recommend you use a thermostatic mixer. The anti-Legionella function is enabled via
this parameter; the temperature to be reached is settable via the P20 parameter and the
hysteresis via the P15 parameter. Suggesting to set the P20 parameter at 60°C and the
P15 parameter at 4°C. 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".
P6 parameter - Silent
This function reduces the sound level (performance can vary from those declared). It can be enabled via
the P6 parameter on the installer's menu. When enabled, the image to the right appears on the display.
