If the LED on your Trane Controller is not lit, it indicates that the power is OFF or there is a malfunction. Try cycling the power to resolve the issue.
What does it mean if the LED is not lit on my Trane Controller?
If the LED is not lit on your Trane Controller, it means that the controller isn't detecting communication. Cycle the power to try and reestablish communication.
Why is my Trane Controller showing a solid red light?
A solid red light on your Trane Controller, when powered, indicates low power or a malfunction. If it's due to low power, it could be undervoltage. If it's a malfunction, try unpowering and then repowering the unit to restore normal operation.
Why does the TX LED constantly blink on my Trane Tracer UC400?
The TX LED on your Trane Controller constantly blinks as it continually searches for devices to communicate with. To troubleshoot this, determine if a device, such as a Tracer SC or BACnet device, is trying to communicate with the controller and if it is capable of doing so. Also, verify if the communication status is consistently down and check the polarity and baud rate.
What does it mean if the LED is not lit on my Trane Tracer UC400 Controller relay output?
If the LED is not lit, it indicates that a relay output is de-energized or there is no power to the board. Try cycling the power to reestablish communication.
How to prevent UC400 Trane Tracer UC400 Controller from going into boot mode?
The controller is placed into boot mode if the service pin is held in when power is applied. Avoid holding the service pin during power-up to prevent this.
Why is the TX LED not lit on my Trane Tracer UC400 Controller?
