Unit displays correct temperature but actual room temperature is much higher or lower than setpoint.

Steps to try:

• Check sensor location: Ensure the sensor is not near sunlight, electronics, or drafts.
• Use fan-only mode: Improve air mixing in the room to reduce stratification.
• Adjust setpoint: Temporarily offset the set temperature to achieve comfort while planning a repair.

When to call a technician: If the sensor is correctly located but readings are inaccurate, it or the PCB may need replacement.
