AbstractAn acutioneering control adapted to be connected to a thermostat control for temperature modifying apparatus wherein the thermostat control includes a temperature sensor which provides a sensed temperature signal. The auctioneering control includes apparatus for sensing absolute humidity and providing a first output signal corresponding to the sensed absolute humidity; first apparatus for comparing the sensed absolute humidity with a predetermined value wherein the first comparing apparatus receives the first output signal and provides a humidity error signal; apparatus for modifying a predetermined temperature setpoint signal responsive to the humidity error signal; apparatus for limiting the modified temperature and providing a limited temperature setpoint signal; and second apparatus for comparing the limited temperature setpoint signal with the sensed temperature signal. The modifying apparatus may further comprise a third apparatus for comparing the predetermined temperature setpoint value with the humidity error signal so as to provide a modified temperature setpoint signal corresponding to the difference between humidity error signal and the predetermined temperature setpoint value.
