What to do if the Omron E5AN-H Temperature Controller shows a large temperature error or S.Err display?
- JJay WangJul 28, 2025
If you are experiencing a large temperature error or seeing an 'S.Err' display on your Omron Temperature Controller, it could be due to a mismatch in the input type setting. To resolve this, verify the sensor type you are using and then reset the input type on the controller to match. Another potential cause is improper installation of the thermometer. Double-check the thermometer's installation location and polarity, ensuring it is correctly installed.
