8.1.2 Memory in the control system
The main circuit board features an EEPROM memory (external to the microprocessor) which stores in
memory data relative to the configuration, description of the cycle, cycle status in case of a power failure,
and any alarm conditions.
The configuration data (entered in the factory using a computer with a DAAS interface) determine the
functionalities of the appliance (number and type of programmes, options, LEDs etc).
