This fan and limit control combines, in one enclosure, a fan switch with an adjustable differential which operates the blower in a forced warm air furnace and a limit switch with a fixed differential which automatically shuts off the burner if the furnace temperature exceeds a predetermined high point. A summer fan switch is incorporated in this control to provide a convenient method for manual operation of the fan for air circulation during the summer.
