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.

E5CN Operating Parameters

The E5CN controller has several mode selections. Within each mode are numerous parameters that can be set.

The factory has set the security level to protect the critical parameters from being accidentally changed. Below is an explanation of the operating modes you will have access to and on the following page are the manufacturers’ default settings.
