Abstract

A household electric user includes an electronic control system that contains an electronic microcontroller (MC), a read and write non volatile memory means (MNV), and means (MC,MS,A1-A5,MZ) for detecting and/or generating variables which relate to the operation status of the electric user. The control system automatically records, within the non volatile memory means (MNV), information of a first type that is indicative of the temporal trend of the status variables during successive predefined reference periods, with the last stored information of the first type causing the elimination of the oldest such information, i.e. with a backward shifting operation of the stored information of the first type. The control system further allows the stored information of the first type to be read outside of the electric user.
