Abstract

Ce dispositif assure une concordance à tout moment entre la température extérieure et celle à laquelle doit correspondre la chaudière. Pour ce faire, deux résistances 1 et 2 sensibles à l'action de la température sont placées l'une à l'extérieur des bâtiments, l'autre sur ou dans le collecteur de la chaudière Ces deux résistances sont montées en série et leurs liaisons 8 et 9 sont insérées dans la branche << à mesurer >> d'un pont de Wheastone 3 qui permet de contrôler la constance de la somme de leurs valeurs ohmiques. Un relais électromagnétique 10, polarisé, ultrasensible, remplit les fonctions du galvanomètre habituel et lors d'un déséquilibre du pont provoque par l'action de son contact 12 la mise en route du brûleur de la chaudière. Un programmateur maintient une température adéquate constante dans les locaux, suivant les heures et jours de la semaine et lors de la non-occupation des lieux.
