What to do if my Trane Tracer ZN524 Controller shows a Low Air Flow—Fan Failure diagnostic?
This indicates that a fan status device is present and fails to close after 1 minute of unit start-up, or it opens for more than 1 minute during normal unit operation.
What happens if my Trane Tracer ZN524 displays 'Maintenance Required'?
This indicates that the fan run-time exceeds the configurable limit.
What to do if my Trane Tracer ZN524 displays 'Invalid Unit Configuration'?
To correct this problem, the unit must be re-configured with a valid configuration.
What to do if my Trane Tracer ZN524 Controller's outside air damper stays closed?
Ensure the wiring between the controller outputs and the outdoor air damper is present and correct for normal damper operation.
What does it mean if the red LED is continuously on in my Trane Tracer ZN524 Controller?
This could mean someone is pressing the Service push button or the controller has failed.
What does it mean if my Trane Tracer ZN524 Controller has a Space Temperature Failure?
This happens if the Tracer ZN524 has validated a space temperature input and then the input becomes invalid.
What does it mean if my Trane Tracer ZN524 has an Outdoor Air Temperature Failure?
This occurs if the Tracer ZN524 has validated an outdoor air temperature input and then the input becomes invalid.
What does it mean if my Trane Tracer ZN524 has a Generic Temperature Failure?
This indicates that the Tracer ZN524 has validated a generic temperature input and then the input becomes invalid.
What does it mean if my Trane Controller has a Humidity Input Failure?
This indicates that the Tracer ZN524 has validated a relative humidity input and then the input becomes invalid.
What does it mean if my Trane Tracer ZN524 has a CO2 Sensor Failure?
This indicates that the Tracer ZN524 has validated a CO2 input and then the input becomes invalid.
