Abstract

La présente invention concerne une technique selon laquelle, même si l'alimentation externe fournie à une unité intérieure est interrompue, l'unité intérieure peut effectuer une commande efficace pour d'autres unités intérieures. Un climatiseur selon l'invention comporte des unités intérieures (1) commandées par une unité extérieure. Une unité intérieure (1) comprend une section de commande principale (11) pour une opération de commande centralisée de l'unité intérieure (1), une section de communication (12) pour communiquer avec l'unité extérieure, une section de détection d'alimentation externe (13) pour détecter que l'alimentation extérieure (EV) fournie à l'unité intérieure (1) est interrompue, et une section de source d'alimentation de secours (15) pour produire une source d'alimentation de secours (VBAT) fournie à la section de communication (12) lorsque la source d'alimentation externe (EV) est interrompue. Dans l'unité intérieure, lorsque la section de détection d'alimentation externe (13) détecte que l'alimentation externe (EV) est interrompue, la section de communication (12) informe l'unité extérieure que la source d'alimentation externe (EV) est interrompue.
