The temperature sensor has a variance of +/- 1°F. A 3-degree discrepancy means you need to apply a permanent correction.
To correct the sensor reading:
- Go to MAIN MENU > SETTINGS > INSTALLATION SETTINGS > THRESHOLDS > TEMPERATURE CORRECTION.
- Adjust the offset by up to +/- 10°F in either direction to match your trusted thermometer.
Important validation steps before you adjust:
- Compare only the thermostat sensor reading, not the average if you have SmartSensors paired.
- Check sensor pairing at MAIN MENU > SETTINGS > SENSORS.
- Seal the hole behind the thermostat with plumber's putty. Air from the wall cavity can influence the sensor.
