Water flow rate [l/h]
The pressure drops in the diagram refer to the average water temperature of 10 °C. The following table shows the correction
to apply to the pressure drops when the medium water temperature varies.

Heating capacity figures refer to maximum fan speed. Performance for other fan speeds can be obtained by multiplying
these figures by the following correction factors:
