Heat production - calculating
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 outdoor 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 heat curve will be adjusted in connection with installation. It must be adapted later on, however, to obtain a
pleasant indoor temperature in any weather conditions. A correctly set heat curve reduces maintenance and saves
energy.

Time interval between collection points of temperature history in minutes. The his-
tory graphs always show the 60 last collection points, which means that the graphs
can display history from 1 hour up to 60 hours ago.
