Why is the TX LED blinking green on my Trane Symbio 500?
- D
  Darrell WeaverAug 7, 2025
  The TX LED on your Trane Controller blinks green because it is constantly searching for devices to communicate with, regardless of whether there is connectivity. To troubleshoot, verify if a device like a Tracer Synchrony or BACnet device is attempting to communicate with the controller and if the controller is capable of such communication. Also, ensure the communication status is not consistently down. Check the polarity and baud rate settings as well.

What to do if the Marquee LED on my Trane Symbio 500 Controller is solid red?
- R
  Robert AllenAug 13, 2025
  If the Marquee LED on your Trane Controller is solid red, it indicates either low power or a malfunction. If it's due to low power, measure the 24 Vac to ensure it falls within the expected range. If it's due to a malfunction, try un-powering and then re-powering the unit to restore normal operation.
