Thermostat shows humidity readings that are clearly inaccurate compared to other hygrometers.

Safety first: No high‑voltage work is required.

• Step 1 – Compare with reference: Place a reliable hygrometer near the thermostat and compare readings over several hours.
• Step 2 – Adjust humidity offset: In the thermostat settings, locate the Humidity Offset or Calibration option and adjust to match the reference meter.
• Step 3 – Improve location: Avoid installing the thermostat in bathrooms, kitchens, or near humidifiers where local humidity fluctuates rapidly.
• Step 4 – Clean vents: Gently blow dust out of the thermostat vents with canned air to ensure the sensor is exposed to room air.
