2.7 Troubleshooting
If a compressor is in an error status, this is shown on the main screen.
The compressor overview shows you which compressor has the error, and the control data is
shown on a red background. An exclamation mark will also be blinking at the top of the screen.
When an alert (not an error) is being signalled by the controller, the touchscreen will show this
by putting a yellow background behind the control data.
