Restoring the Process Air Temperature Controller (E5CN) to Factory Settings
If the preset parameters on the controller have been tampered with and it no longer properly
controls temperature and displays dew point, you can restore the controllers to the factory
setup. Call the Service Department for detailed instructions.

changed. Below is an explanation of the operating modes you will have access to and on the
