ABSTRACT:
A humidity controller includes a set point device, which establishes a set point for humidity within a given area, and a humidity sensor, which senses the humidity within the area, connected in a sensing network which provides a differential output voltage indicating deviations of the humidity from the set point. The output voltage selectively enables differential threshold detecting circuits which energize humidifying and dehumidifying apparatus to return the humidity to the set point value. A differential range adjust, which establishes a turnon threshold for the detecting circuits, is derived from the set point such that the turnon differential for the detecting circuits remains fixed regardless of the set point value.
