LED diagnose and remedy
10
Led color Meaning Diagnostic Cause Remedy
Continuous green Normal running Pump run as expected or is faced to a phenomenon thatshortly affects its running
Normal operation
Quick green blinks Air venting routine running
Pump runs during 10min in air venting function
Afterwards the installer has to adjust the targeted performance
Red /green blinking Abnormal situation (pump functional but stopped)
Pump will restart by itself after the abnormal situation disappeared
1. Undervoltage or Overvoltage : U<160V or U> 253V
2. Module overheating : T° inside motor too high
1. Check voltage supply : 195V<U<253V
2. Check water & ambient T°
Red blinking Stopped (e.g. pump blocked)
Reset the pumpCheck LED signal
Pump cannot restart itself due to a permanent failure
Change pump
No LED No power supply No voltage on electronics 1) Pump is not connected to power supply2) LED is damaged3) Electronics are damaged
1) Check cable connection2) Check if pump is running3) Change pump

Constant Pressure Head Difference (∆p-c)
∆p-c
The pump is able to maintain a constant pressure by reducing the speed when the pressure losses of the system increase
Variable Pressure Head Difference (∆p-v)
∆p-v
The pump is able to adapt the head pressure between setting point H and H/2 by reducing the speed when the pressure losses of the system increase
∆p-v versus ∆p-c
