Controlling Engine Temperatures

OPERATION

Switch is normally closed at temperatures below setpoint causing the load to remain energized. When setpoint temperature is reached, switch opens and load is turned off. Temperature must then fall below setpoint minus hysteresis value before switch will close and the load becomes energized again.
