What to do if Trane AdaptiView Monitor displays 'Display Failed to Establish Communication'?
- DDavid GarrettJul 31, 2025
If the Trane Monitor displays the error message 'Display Failed to Establish Communication,' it indicates that communication has not been established. Check the power and communication cable connections. It's also possible the UC800 has an invalid configuration, in which case you should download a valid configuration using the Tracer TU service tool.
