The "PLUS" is a comfort function which is factory set to be
active but can be deactivated.
This function enables the appliance to automatically switch on
the electrical heater together with the heat pump cycle when
the air temperature is below 10 °C, the water temperature at
the bottom is cold, and a rapid temperature decrease at the top
of the tank is detected. Hence, by activating the auto boost, the
appliance will initiate a fast recover at the top of the tank to face
a potential lack of hot water. Once a hot water buffer is created
at the top, the appliance will proceed the recover by using the
heat pump cycle only.
