A control system for an electrically energized humidifier used with a hot-air furnace including an electric time-delay circuit and control means for manually adjusting the time delay. Each time the thermostat for the system energizes the furnace the humidifier is energized for the predetermined time delay or until the furnace is de-energized, whichever occurs first. The time delay is manually adjusted so that it is longer than the energization cycle of the furnace in warm weather and shorter than the energization cycle of the furnace in cold weather. It is also manually adjusted so that in cold weather at the maximum energization cycle, the humifidier does not produce condensation within the building. The relative humidity of the conditioned air thus decreases proportionately to increases in the atmospheric temperature.

A control for use with a humidifier, capable of drawing electrical power from an electrical power source, adapted to be coupled to a hot-air furnace controlled by a thermostat so that moisture is added to heated air leaving said furnace at such time as said humidifier is energized, said thermostat controlling energization of said furnace and providing relatively short furnace operation cycles in warm weather and relatively longer furnace operation cycles in colder weather, said control being connected to said humidifier and to said electrical power source for said humidifier to energize said humidifier for a predetermined continuous period of time within said furnace operation cycle.
