What does it mean if my Trane Tracer ZN524 Controller has a Generic AIP Failure?
- MMark GarciaSep 8, 2025
This indicates that the Tracer ZN524 has validated a generic analog input and then the input becomes invalid.
What does it mean if my Trane Tracer ZN524 Controller has a Generic AIP Failure?
This indicates that the Tracer ZN524 has validated a generic analog input and then the input becomes invalid.
What does it mean if my Trane Controller has a Local Fan Mode Failure?
This indicates that the hardwired fan mode input to the Tracer ZN524 controller is present and then becomes invalid.
What does it mean if my Trane Controller has a Local Setpoint Failure?
This indicates that the hardwired setpoint input to the Tracer ZN524 controller is present and then becomes invalid.
What does it mean if the green LED activity LED blinks (2 blinks per second) on my Trane Tracer ZN524 Controller?
The controller is in manual output test mode, and one or more diagnostics are present.
What does it mean if the yellow LED activity LED is continuously on on my Trane Controller?
This indicates an abnormal condition or extremely high traffic on the link.
What does it mean if my Trane Tracer ZN524 Controller displays a Discharge Air Temperature Limit?
This occurs when the discharge air exceeds the low limit setpoint and the unit cannot correct it by altering capacity.
