The weather controlled heating curve shows that the temperature of the return (heating water
returning to the heat pump from heating bodies) depends on the temperature of air outside the
building. The lower the external air temperature, the higher the calculated needed temperature of
the return.
The weather controlled heating curve
The appropriate heating temperature setting is essential for ensuring the desired comfort. It
depends on the characteristics of the house and heating bodies as well as the project temperature.
The table below lists the recommended settings which can help you decide on the appropriate
parameters of the weather controlled heating.
