1. A damper control device comprising, in combination:
- a damper movable between a closed position and an open position;
a thermoelectric device;
a battery having a voltage; and
a controller comprising a comparator circuit which compares an input voltage from the thermoelectric device with a reference voltage based upon the voltage of the battery;
wherein when the input voltage is greater than or equal to the reference voltage, the comparator circuit transmits a damper signal to move the damper to the open position.

Abstract
A millivolt damper control device comprises a damper movable between a closed position where a flue is blocked and an open position, a thermoelectric device having an input voltage, a battery having a voltage, and a controller comprising a comparator circuit which compares the input voltage with a reference voltage based upon the voltage of the battery. When the input voltage is greater than or equal to the reference voltage, the comparator circuit transmits a damper signal to move the damper to the open position.

8. A damper control device comprising, in combination:
-
a damper;
a motor which moves the damper between a closed position and an open position;
a thermoelectric device;
a battery having a voltage; and
a controller comprising a comparator circuit which compares an input voltage from the thermoelectric device with a reference voltage based upon the voltage of the battery;
wherein the comparator circuit maintains a predetermined time delay corresponding to a time between when the input voltage is removed from the comparator circuit and when the reference voltage is reapplied at the motor. - View Dependent Claims (9, 10)
