CA 2415959

An electrical control system is disclosed for controlling a plurality of variable transmittance windows (44a). To achieve these and other aspects and advantages, the electrical control system of the present invention comprises a master control circuit (1000) for supplying control signals representing transmittance levels for the variable transmission windows, and a plurality of window control circuits (1100a) coupled to each of the master control circuit. Each window control circuit (1100a) controls the transmittance of at least one of the variable transmission windows (44a) in response to control signals received from the master control circuit (1000). Also disclosed are several window constructions that enable variable transmission windows (44a), such as electrochromic windows, to be used in architectural windows having a moving sash. Also disclosed are several window constructions that enable variable transmission elements to be more easily installed and replaced.

L'invention concerne un système de commande électrique qui contrôle plusieurs fenêtres de transmission variable. Pour obtenir cela et d'autres aspects et avantages, le système de commande électrique de l'invention comprend un circuit de commande maître qui fournit des signaux de commande correspondant à des niveaux de transmission destinés aux fenêtres de transmission variable, et plusieurs circuits de commande de fenêtres couplés à chaque circuit de commande maître. Chaque circuit de commande de fenêtres contrôle la transmission d'au moins une des fenêtres de transmission variable en réponse à des signaux de commande reçus du circuit de commande maître. L'invention concerne également plusieurs constructions de fenêtres qui activent des fenêtres de transmission variable, telles que des fenêtres électrochromiques, devant être utilisées dans des fenêtres architecturaux comportant un volet à guillotine mobile. L'invention concerne en outre plusieurs constructions de fenêtres qui activent des éléments de transmission variable afin qu'ils soient installés et remplacés plus facilement.
