Abstract

L'invention concerne un système de climatisation. Le système de climatisation est connecté dans une ligne électrique triphasée, et est couplé à un coupleur triphasé au moyen de la ligne électrique triphasée. Le système de climatisation comprend une unité extérieure, et l'unité extérieure comprend une passerelle de communication de support de ligne électrique et un dispositif de commande. Le dispositif de commande est configuré pour: commander la passerelle de communication de porteuse de ligne électrique pour envoyer un signal de mise en réseau au coupleur triphasé; et commander la passerelle de communication de porteuse de ligne électrique pour recevoir un premier signal de réponse transmis par le coupleur triphasé et en réponse au premier signal de réponse, effectuer une mise en réseau avec l'envoi par un premier dispositif du premier signal de réponse. Le coupleur triphasé est en outre configuré pour, lorsqu'une adresse cible portée par le premier signal de réponse est la même qu'une adresse de la passerelle de communication de porteuse de ligne d'alimentation enregistrée par le coupleur triphasé, transmettre le premier signal de réponse à un dispositif connecté à n'importe quelle ligne d'alimentation de la ligne d'alimentation triphasée.
