Identify the Calibration Error
 

For customers in St. Louis, our experts can help quickly pinpoint the source of calibration issues.

 

• Review the display for any error codes or unusual readings that indicate calibration issues.
• Make a note of the error details observed, including any warning messages from the thermostat.
• Consult the Trane AC thermostat manual or manufacturer’s website to decode the error message.

 
Check the Thermostat Batteries
 

• Remove the thermostat cover and inspect the batteries for corrosion, leakage, or low charge.
• Replace the batteries if they are old or have signs of diminished capacity.
• Reinsert the batteries correctly and monitor the display to confirm if the calibration error is cleared.

 
Inspect and Reset the Wiring Connections
 

• Turn off the power to the HVAC system at the breaker before inspecting the thermostat wiring.
• Examine all wiring connections ensuring that no wires are loose, corroded, or improperly connected.
• Disconnect and reconnect any wires that may have a poor or unstable connection, following the wiring diagram provided by Trane.

 
Perform a System Reset
 

• Switch off the thermostat and HVAC system for a few minutes to allow an internal reset.
• Turn the power back on and reinitialize the thermostat settings, following the manufacturer’s reset instructions.
• Observe if the calibration error has disappeared; if not, it may require a manual calibration process.

 
Recalibrate the Thermostat Manually
 

• Locate the calibration controls on the thermostat. These might be a set of dials or menu settings allowing adjustment.
• Adjust the calibration settings gradually while monitoring the temperature readings to align with the actual room temperature.
• Consult the user’s manual for the recommended settings and procedures specific to your Trane model.

 
Update the Thermostat Firmware (if applicable)
