Title:
MILLIVOLT DAMPER CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2005/108870
Kind Code:
A2
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 7 comparator circuit which compares the input voltage with a reference voltage based 8 upon the voltage of the battery. When the input voltage is greater than or equal to 9 the reference voltage, the comparator circuit transmits a damper signal to move the damper to the open position.
