Abstract

Cette invention se rapporte à un système de commande de chauffage permettant d'économiser de l'énergie ainsi qu'à son procédé de commande de chauffage, dans lequel l'énergie du système permettant de chauffer des pièces dans un logement est réduite en ne chauffant séparément les pièces individuelles que pendant des intervalles de temps particuliers en termes d'heure/de jour sélectionné en considérant chaque séquence de la vie de tous les jours de l'utilisateur de la pièce. À cet effet, dans le système, une pluralité d'intervalle de temps d'économie en termes d'heure/de jour sont stockés à l'avance dans une mémoire. Si l'utilisateur sélectionne et règle au moins l'un de la pluralité des intervalles de temps d'économie pour chauffer une pièce, un dispositif d'ajustement de vannes fournit en sortie des signaux de commande de vannes vers un contrôleur de vannes afin d'ouvrir ou de fermer une vanne automatique correspondant à la pièce. Le dispositif d'ajustement de vannes peut être conçu pour être autonome ou de type intégré, un type intégré dans lequel le dispositif d'ajustement de vannes et un dispositif d'ajustement de chaudière sont incorporés dans un dispositif d'ajustement intégré.
