Abstract

L'invention apprend et présente des systèmes (100), des dispositifs (1000) et des procédés de commande de l'automatisation de diffuseurs de ventilation. Dans une exécution elle porte sur un système (100) d'articulation d'un diffuseur de chauffage ou de climatisation. Le système comporte normalement une alimentation locale (195), un récepteur de signaux sans fil (160), un moyen d'enclenchement d'un moteur (170), un moteur (180), et un élément mobile (190).
