Parameters Description
P1030
The system tries to control the motor speed accordingly to the Manual Speed Setpoint (P1051 or AI2). With limited
0 radiation, the system controls the DC bus voltage, causing the pump to run at maximum speed possible to reach
the Manual Speed Setpoint.
The system operates through the DC voltage control and when the solar radiation allows controlling the Output
1 Pressure. With limited radiation, the system controls the DC bus voltage, causing the pump to run at maximum
speed possible to reach the Pressure Setpoint.
The selection of Manual or Automatic Mode is made by DI5 (0=Manual / 1=Automatic). The DI5 must also be
2
programmed for this function, check the parameter P0267.
Disable the Pressure Control. The system controls the DC bus voltage, causing the pump to run at maximum speed
3
possible, limited to the maximum speed (P0134).
