Abstract
A metal sheathed heater includes a solid state control device that allows the metal sheathed heater to be more efficiently operated. The control device supplies or terminates power to the heater according to certain conditions. Further, the control device uses predetermined time periods to control power to the heater. Thus, the heater is not kept on unnecessarily.
