The pump speed can be selected by adjusting the red knob on the pump. The point indicated by the notch indicates the
pump speed.
The default setting is the maximum speed (3). If the water flow in the system is too high, the speed can be set at low (1).
The relationship between the external available static pressure and the water flow rate is indicated in the chart below:

DANGER
If the operation status of the pump needs to be checked when the unit switches on, please do not touch the internal
components of the electric control box to avoid electric shocks.
10.4.1 Troubleshooting at first installation (models 4-16 kW).
• If nothing is displayed on the control panel, check for one of the following faults before diagnosing any error codes.
- Disconnection or wiring error (between the power supply and the unit and between the unit and the control panel).
- The fuse on the PCB could be blown.
• If the control panel displays "E8" or "E0" as error code, there could be air in the system, or the water level in the system
might be lower than the minimum required.
