cut off thermostat the output of the temperature sensor is below a certain value, the auxiliary current circuit is activated intermediate, magnetizing the solenoid switch, activating the heater when the temperature is high enough, the output of the secondary current is terminated, the switch is off . Heating is stopped. Since the delay characteristics of the heating, the system is maintained within a temperature range depends on the accuracy of the range instrument precision. This is cut off thermostat basic working process.
