Environmental control system

Abstract

An environmental control system utilizing a single moisture and dust impervious temperature probe of a multistage thermostat to both control a fogging system in a hog house or the like and other temperature altering devices such as an adjustable ventilation system, fans, heaters and the like. In a cooling cycle of operation, when the sensed temperature rises to a first preselected level, one of the stages causes actuation of one of the temperature cooling apparatus. If the temperature continues to rise to another excessively higher preselected temperature, another stage causes actuation of the fogging system. When the sensed temperature then drops by a preselected amount, the fogging system is deactuated. The actuation and deactuation temperatures are selectively variable to minimize excessive fogging. In the heating cycle of operation, heating devices are suitably controlled in accordance with temperatures.
