THERMAL DISINFECTION FUNCTION (ANTI-LEGIONELLA)
The anti-Legionella function is activated by default. It consists of a water heating/60°C temperature mainte
nance cycle for 1 hour which has a thermal disinfection action on the relative bacteria.
The cycle starts when the product is started up and when it is restarted after a power outage. If the product
always functions at temperatures lower than 55°C, the cycle is repeated after 30 days. When the product
is switched o, the anti-Legionella function is deactivated. If the equipment is switched o during the anti
Legionella cycle, the product switches o and the function is deactivated. At the end of the cycle, the use
temperature returns to the temperature previously set by the user.
To activate/deactivate the function while the unit is running, hold down the “MODE” key for 3 sec. Set “Ab 1” (to
activate the function) or “Ab 0” (to deactivate it) with the knob, and confirm by pressing “SET”. To confirm that
the function has been activated/deactivated as desired, the unit returns to normal operation.
RESET/DIAGNOSTICS
When any of the operation problems occur, the appliance goes into "fault status" and the corresponding error
code flashes on the display (for example, E01).The error codes are the following:
E01 - internal error of the board
E04 - impressed current anode malfunction (corrosion protection is not guaranteed)
E09 - excessive number of resets in fifteen minutes
E10 - broken temperature probes (open or short circuited) - boiler outlet
E11 - excessive water temperature detected by single sensor - boiler outlet
E12 - general excessive water temperature (circuit board fault) - boiler outlet
E14 - Failure to heat water with powered healing element - boiler outlet
E15 - overheating caused by lack of water - boiler outlet
E20 - broken temperature probes (open or short circuited) - boiler inlet
E21 - excessive water temperature detected by single sensor - boiler inlet
E22 - general excessive water temperature (circuit board fault) - boiler inlet
E24 - failure to heat water with powered heating element - boiler inlet
E25 - overheating caused by lack of water - boiler inlet
E61 - internal malfunction of the circuit board (NFC communication)
E62 - internal malfunction of the circuit board (NFC data damaged)
E70 - Limescale - Limited mode
Error reset: reset the appliance by switching iio and on from the ON/OFF buttonRif.A).
If the cause of the malfunction disappears immediately when reset, the appliance resumes its regular opera-
tion. On the contrary, if the error code continues to appear on the display: contact the Technical Service Centre.
