Water temperature that can be reached in heat
pump mode P106 (°C)
The maximum temperature of the domestic hot water using only the heat pump depends on the air temperature.
At an air temperature of 35 °C, the maximum water temperature that can be reached is 60 °C. At 45 °C, the maximum tem-
perature is reduced to 55 °C. The water temperature is reduced by 1 °C for every 2 °C air temperature.
The temperature difference between the set value and the maximum value that can be reached in the heat pump mode is
regulated by the immersion heater.
