Thermostat shows humidity far higher or lower than actual; dehumidification or humidification behaves erratically.

Safety first: No high-voltage work is required.

Steps to troubleshoot:

• 1. Compare readings: Place a reliable hygrometer near the thermostat and compare humidity readings.
• 2. Adjust humidity offset: Use the thermostat’s humidity calibration setting to align readings with the reference instrument.
• 3. Improve location: Avoid installing the thermostat near bathrooms, kitchens, or humidifiers that can skew readings.
• 4. Replace thermostat: If readings remain unstable or far off even after calibration, replace the Bryant smart thermostat.
