Abstract

L'invention porte sur un système de conditionneur d'air numérique à éléments multiples télécommandé et à un procédé de réglage de groupe correspondant qui s'applique à des appareils électroménagers télécommandés. Selon le procédé, un ordinateur invite tous les modules de communication à émettre et envoie ensuite des informations de groupe à chaque module de communication, le module de communication acquérant en même temps des informations d'état de fonctionnement de chaque unité interne reliée au module de communication (S5). A l'étape suivante, on procède à un réglage de groupe, c'est-à-dire que l'ordinateur envoie le numéro de groupe d'un ensemble d'unités internes nécessitant un réglage et des informations de réglage à chaque module de communication, et chaque module de communication envoie les informations de réglage aux unités internes reliées aux modules de communication correspondant au numéro de groupe, le réglage s'achevant avec la réponse des unités internes concernées (S6). Le système de conditionneur d'air centralisé télécommandé de l'invention comprend une machine supérieure équipée d'un dispositif qui a pour fonction de recevoir et d'envoyer des informations, et une machine inférieure qui contient au moins un ensemble d'unités comprenant un module de communications, une unité externe et une pluralité d'unités internes. La machine supérieure et les unités internes de la machine inférieure communiquent entre elles via les modules de communication. L'invention offre l'avantage de permettre aux utilisateurs de régler les unités internes sous la forme d'unités machine ou de groupes définis par l'utilisateur.
