6-2 Determining Temperature Controller Errors or Sensor Errors
Using a Thermocouple
If the controller displays a temperature that is close to room temperature (70ºF/21ºC) when
you short-circuit controller input terminals, the controller is normal and the sensor is probably
broken, short-circuited, or incorrectly wired.
