DEFAULT SETTINGS

The appliance is manufactured with a series of default modes, functions or values, as indicated in the table below:
PARAMETER
WORKING MODE
MAX. TEMPERATURE SETTABLE WITH THE HEATING ELEMENT
MINIMUM SETTABLE TEMPERATURE
MAX. TEMPERATURE SETTABLE WITH THE HEAT PUMP *
ANTIBACTERIAL PROTECTION
HOLIDAY MODE
DEFROST (active defrost activation)
HC-HP (two-tier rate operation mode)
* In Green mode, the maximum temperature with the heat pump adjusts to 55°C if air temperature is above 20°C.
FAULTS
As soon as a fault occurs, the appliance enters into the fault mode while the display emits flashing signals and visualises the error code. The wa-
ter heater will continue supplying hot water if the fault affects only one of two the heating units, by activating the heat pump or heating element.
If the fault involves the heat pump, the symbol "HP" will flash on the screen, while the heating element symbol will flash if the fault involves it. If
both components are affected, both symbols will flash.
CAUTION!
Before intervening on the product by following the indications below, check the correct electrical connection of the components to the
