Title (EN) DISTRIBUTED APPLIANCE CONTROL SYSTEM HAVING FAULT ISOLATION
(FR) SYSTEME DE COMMANDE D'APPAREIL REPARTI A LOCALISATION DES PANNES
Abstract:
(EN) An appliance controller suitable for controlling a heating appliance (e.g., gas-fired water heating apparatus) having a distributed control system. The distributed control system includes a host computer and one or more heating control units. In accordance with a preferred embodiment, each heating control unit takes the form of an ignition control for controlling operation of a gas-fired burner for a multi-stage boiler. The appliance controller also includes a fault isolation system for isolating the source of a malfunction, and providing service personnel with status information regarding components of the appliance. The appliance controller is adapted to provide variable output signals for adaptive control of some appliance components, such as a blower or a circulation pump.
(FR) L'invention concerne un dispositif de commande d'appareil permettant de commander un appareil de chauffage (par exemple, un chauffe-eau au gaz) comprenant un système de commande réparti. Ce système de commande réparti comprend un ordinateur hôte et une ou plusieurs unités de commande de chauffage. Selon un mode de réalisation privilégié, chaque unité de commande de chauffage se transforme en une commande d'allumage de manière à commander le fonctionnement d'un brûleur au gaz pour une chaudière poly-étagée. Le dispositif de commande d'appareil comprend également un système de localisation des pannes conçu pour localiser la source d'un défaut de fonctionnement, et pour fournir à la personne chargée de la maintenance et de l'entretien des informations d'état concernant les composants de l'appareil. Le dispositif de commande d'appareil est conçu pour fournir des signaux de sortie variables servant à exécuter les commandes adaptées pour certains composants de l'appareil, tels que le ventilateur ou la pompe de circulation.
