Humidity comfort offset circuit

Claim 1

A humidity comfort offset circuit having output means adapted to be connected to a bridge circuit of a thermostat to adjust the thermostat to maintain a comfortable temperature as humidity changes, including: humidity responsive circuit means having output circuit means adapted to be connected to said thermostat bridge to change the balance of said bridge as humidity changes to maintain a comfortable temperature; said humidity responsive circuit means including a capacitive element that changes in capacity with change in humidity; power supply means to energize said humidity responsive circuit means to supply said output circuit means with a signal that varies with humidity; said power supply means providing an alternating current potential to said humidity responsive circuit means to periodically charge said capacitive element; said power supply means further providing a direct current potential to said humidity responsive circuit output means to in turn provide said signal that varies with humidity; said output circuit means being so arranged and designed as to have an output range with at least one humidity value being equal to a balance value of said bridge so that said humidity responsive circuit has no effect on said thermostat at said value; and said thermostat temperature control is decreased as humidity increases, and said thermostat temperature control is increased as humidity is decreased from said balance value.
