Abstract

Un thermostat comprend un boîtier, une interface utilisateur et un système de traitement configuré pour commander un système CVCA (Chauffage, Ventilation et Climatisation) en utilisant des valeurs de point de régulage de température. Le thermostat peut également comporter une pluralité de connecteurs CVCA configurés pour recevoir des conducteurs de commande CVCA correspondants, et un module de détection de connexion configuré pour déterminer les identités de connecteurs CVCA dans lesquels des conducteurs correspondants ont été insérés. Le système de traitement peut en outre être configuré pour identifier, sur la base du sous-ensemble de connecteurs CVCA si (i) une seule configuration possible du système CVCA est ainsi indiquée ou (ii) si de multiples configurations possibles du système CVCA sont ainsi indiquées, résoudre une configuration particulière parmi celles possibles du système CVCA pouvant être appliquée sur la base d'une réponse de l'utilisateur à une demande présentée sur l'interface utilisateur, et faire fonctionner le système CVCA conformément à la configuration du système CVCA.
