ABSTRACT:
An automatic temperature control system and method for maintaining a predetermined temperature in an enclosed space, wherein the temperature in a heat sink is sensed and compared with the outside temperature to anticipate whether a heating or cooling mode is or may be required. When a mode is selected, a "readiness" state signal is supplied to a preset control in the enclosed space. When the preset temperature is reached in the enclosed space, the preset control energizes the appropriate heating or cooling device to maintain the preset temperature in the enclosed space.
