The heating system is normally configured for automatic house heating/DHW at commissioning. An appropriate heating curve and a
desired room temperature are selected by the installer. The heat pump will adjust the house heating water temperature in accordance
with the outside air temperature. The maximum water temperature for house heating is 50°C. The AUTO mode is for both comfortable
house heating and energy saving.
The heating function can be set to MANUAL mode, then the heat pump will produce a constant supply line temperature following the
setting in the control system.
The picture below shows a simplified view of the recommended heating curves and the temperature working range in AUTO mode.
