Abstract
A damper control system having energy efficient mechanisms. The system may use a heat-to-electric power converter such as a thermopile. Heat may come from a pilot light used for igniting a flame for an appliance. The system may store electric energy in a storage module which could be a sufficiently large capacitor. The system may monitor the position of a damper in a vent or the like and provide start and stop movements of the damper using minimal energy. One way that the system may control electrical energy to a damper motor or another electrical mover of the damper is to use pulse width modulated signals.
