Once the new board is installed, login to the Webbox using the Service level login.
Navigate to the "Service" tab in the top left. Select "Delete" for "Unit Descriptions" and save.
Navigate to the "Plant" tab, then "Detection" and "Start Detection". This will identify the newly installed board.
Once the board is connected, click on the serial number, then the "Parameters" tab, find the parameter and enter the correct "Serial Number", then click "Save" at the bottom.
The board will no longer communicate. Repeat steps 1-3 to identify the board with your programmed serial number.
Make sure all of the parameters are configured correctly for your plant.
