The heat curve can also be fi ne-tuned. Fine-tuning means that the heat
curve is offset in parallel. Fine-tuning is done from the Temp. fi ne-tune
menu. The diagram for fi ne-tuning shows how the dashed line has been
offset upwards in parallel. This means the heating has been fi ne-tuned in a
positive direction and the heat pump will be instructed to maintain a higher
temperature on the return water at all outdoor temperatures.
