A pumping system for moving water of a swimming pool includes a water pump, an infinitely variable speed motor, and an arrangement for operating the motor. In one example, the pumping system includes a memory configured to store a plurality of retained speed values, an arrangement for providing a plurality of retained speed values to the memory, and an arrangement for reading a selected one of the plurality of retained speed values from the memory. In addition or alternatively, the pumping system includes a storage medium for digitally storing a plurality of pre-established motor speed values and an arrangement for receiving input from a user to select one of the pre-established motor speeds. In addition or alternatively, the pumping system further includes an arrangement for restarting operation of the motor at a previously selected speed value when power supplied to the motor is interrupted during operation of the motor. A method for controlling the pumping system is also provided.
L'invention porte sur un système de pompage mettant en mouvement l'eau d'une piscine et comportant: une pompe à eau; un moteur à vitesse variable en continu; et un dispositif de commande du moteur. Dans un exemple, le système de pompage comporte; une mémoire stockant différentes valeurs de vitesses retenues; un dispositif d'introduction dans la mémoire des valeurs de vitesses retenues; et un dispositif de lecture de l'une des valeurs de vitesses retenues en mémoire. En plus ou en variante, ledit système comporte un moyen de stockage numérique de plusieurs valeurs de vitesse préétablies et un dispositif recevant des instructions de l'utilisateur pour choisir l'une des vitesses préétablies. En plus ou en variante, ledit système comporte un dispositif redémarrant le moteur à une vitesse précédemment choisie quand l'alimentation du moteur a été interrompue. L'invention porte également sur une méthode de commande du système de pompage.
