The electronic control unit (E.C.U.) consists of:
- input circuits for filtering, conditioning and digitizing the signals received from the system via wiring;
- integrated logic circuits for processing signals and managing program memories;
- specific data memory for the application for which it is intended;
- output or power stages for driving, with sufficient current intensity, the regulating solenoids, recy­
cling pump motor and fault warning light.
