Fine-tune the heat curve

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.

Outdoor temperature (ºC)

Return temperature (ºC)

By using the menu dial on the control panel

the ﬁ ne-tuning line has been moved up so the

heat pump produces more heat.

In warm weather (above +5ºC):

If the indoor temperature is not satisfactory when it is above +5°C

outdoors, the curve may be offset in the Temp. ﬁ ne-tune menu as follows:

1. Press the Heat button in the initial menu.

2. Turn the menu dial clockwise until you reach the menu Temp. ﬁ ne-

tune.

3. Press the Adjust button.

4. Turn the menu dial clockwise to increase the heating. Turn the menu

dial anti-clockwise to lower the heating. Adjust in small increments,

0.2-0.6 units, is usually enough.

5. Save the new value by pressing the Save button.
