release the two keys only when the letters EE appear. In this case the ACTIVE DRIVER restores the factory
settings. When it has finished setting all the parameters the ACTIVE DRIVER returns to normal operation.
In this phase, in the models in which RC is active, the motor current is set at 0 as factory
default, so when you try to start the electropump it will immediately give the error EC. Go to
the installer’s display and settings menu (keys MODE and SET and – for 5 seconds ) and set the
correct motor data plate current (parameter rC as in paragraph 8.5.1.)

ERROR AND STATUS CONDITIONS (ref. Table no. 14 page 53)
The ACTIVE DRIVER is equipped with protection systems to preserve the pump, the motor, the
supply line and the ACTIVE DRIVER itself.
If one or more protections trip, the one with the highest priority is immediately notified on the display.
Depending on the type of error the electropump may switch itself off, but when normal conditions are restored
the error status may be cancelled immediately or only after a certain time, following an automatic reset.
