Des températures cibles individuelles pour chaque pièce, acquises à partir d'une borne d'entrée/sortie (19), et une température extérieure, acquise par un capteur de température extérieure (7), sont entrées dans une unité de réglage de mode (32). Sur la base des températures cibles individuelles et de la température extérieure, l'unité de réglage de mode (32) règle un mode de refroidissement et une température de consigne de refroidissement pour l'utilisation pendant le fonctionnement du mode de refroidissement, ou règle un mode de chauffage et une température de consigne de chauffage pour l'utilisation pendant le fonctionnement du mode de chauffage, pour chacun du premier climatiseur (9a), du deuxième climatiseur (9b), et du troisième climatiseur (9c).
