8.2 Calculating heat production
The heat curve settings the are adjusted by the installer during installation/commissioning, but fine tuning to
the specific house conditions and individual preferences may be required after some time to obtain a pleasant
indoor climate in all weather conditions. A correctly set heat curve reduces maintenance and saves energy.
The indoor temperature is adjusted by changing the heat pump’s heat curve, which is the control system’s tool
for calculating what the supply temperature should be for water that is sent out in the heating system.
The heat curve calculates the supply temperature depending on the outdoor temperature. The lower the out-
door temperature, the higher the supply temperature. In other words, the supply temperature of the water fed
to the heating system will increase linearly as the outdoor air temperature falls.

The set value 40 for heat curve
The heat curve number is indicating the temperature of the water supplied to the heating system ("supply line
temperature") at an outdoor temperature of 0 °C.
