Regulation information
Heat production - calculating
The indoor temperature is adjusted by changing the heat pump’s heat curve, which is the
control computer’s tool for calculating what the supply temperature should be for water that
is sent out in the heating system. The supply temperature is calculated from the outdoor
temperature and two adjustable values: CURVE and ROOM. The lower the outdoor tem-
perature, the higher the supply temperature. In other words, the supply temperature of the
water fed to the heating system will increase exponentially as the outdoor temperature falls.
The heat curve will be adjusted in connection with installation. It must be adjusted later on,
however, to obtain a pleasant indoor temperature in any weather conditions. A correctly set
heat curve reduces maintenance and saves energy.
