If your thermostat is displaying a higher indoor temperature than what you have set, it can be an indication of a few potential issues. Here are a few possible explanations:
Placement of the thermostat: The thermostat's location within your home can affect its accuracy. If it's placed near a heat source or in a particularly warm area, it may register a higher temperature than the rest of the house. This can lead to the system shutting off prematurely, leaving other areas of your home cooler than desired.
Temperature variations: Temperature variations can occur naturally within a home, especially in larger spaces or multi-level houses. In such cases, the thermostat might be positioned in an area that experiences different temperature levels than other parts of the house. This can result in a disparity between the displayed temperature and the temperature in other areas.
Calibration issues: Over time, thermostats can experience calibration problems. If the thermostat is not calibrated correctly, it may display inaccurate temperature readings. This can lead to the thermostat showing a higher indoor temperature than what it is set at.
Equipment malfunctions: In some cases, there might be issues with the heating or cooling equipment itself. Faulty sensors, malfunctioning components, or incorrect wiring can cause the thermostat to display inaccurate temperature readings.
If you notice a consistent discrepancy between the set temperature and the displayed temperature on your thermostat, it may be worth investigating further. Consider checking the thermostat's placement, ensuring it is away from heat sources and in an area that accurately reflects the average temperature of your home. If the issue persists, you might want to consult an HVAC professional to inspect and potentially recalibrate or repair the thermostat or HVAC system.
