ZETTLER CONTROLS electric heat sequencers are used to stage electric heat to prevent circuit overload. Common applications include electric furnaces, baseboard heaters, heat pump blower and heating element controls. The device uses a positive temperature coefficient (PTC) heater and bimetal disc(s) to initiate the switching action. The PTC is self-current limiting, ensuring stable switching over a wide range of voltages.
