Abstract

L'invention concerne un climatiseur et un procédé de réglage de groupe, le climatiseur comprenant : une pluralité d'unités intérieures ; une pluralité de dispositifs de commande à distance reliés à une ou à plusieurs unités intérieures afin de commander le fonctionnement des unités intérieures reliées auxdits dispositifs ; et un dispositif de commande centralisée destiné à commander les unités intérieures et les dispositifs de commande à distance. Une adresse d'unité consistant en des informations d'identification uniques est définie pour chacune de la pluralité d'unités intérieures. Le dispositif de commande centralisée fixe le fonctionnement de la pluralité d'unités intérieures à un premier état de réglage et envoie, à l'unité intérieure ayant l'adresse d'unité fixée à un minimum ou à un maximum parmi les unités intérieures réglées dans le premier état de réglage, un signal de commande destiné à modifier le fonctionnement du premier état de réglage à un second état de réglage, puis fixe, en tant que même groupe, la ou les unités intérieures ayant répondu au signal de commande dans une période de temps d'attente prédéfinie.
