CONTROL SYSTEM FOR A HOUSEHOLD APPLIANCE, WATER TREATMENT SYSTEM CONTROLLED BY THE SYSTEM AND RELATED PROGRAM AND METHOD

Control system (8) for a household appliance (1), at least adapted to control a water treatment system (2), the latter comprising ion-exchange resins.The control system (8) being adapted to establish different hardness levels of water to be used in said household appliance (1) and, for each established hardness level, when it is necessary to carry out a procedure for regenerating the resins of the system (2).The control system (8) comprising: at least one storage medium (82) containing information and data about the management and control of the system (2); and at least one processing unit (81) adapted to process the data contained in said storage medium (82), for the purpose of appropriately controlling the system (2) so as to be able to change the hardness of the water to be used in said household appliance (1) and conveniently request the execution of a procedure for regenerating the resins of said system (2).The storage medium (82) is adapted to allocate memory for at least two threshold values for each hardness level established by the control system (8).Said at least two threshold values corresponding to as many water quantities to be supplied to the system (2), whereupon it is necessary to supply a suitable quantity of a regeneration liquid or fluid in contact with said ion-exchange resins of said system (2).
