Room temperature overshoots setpoint by several degrees before heater turns off.

Safety first: Turn OFF power at the breaker before relocating the thermostat.

Steps to improve control:

• Check mounting location: Ensure the thermostat is installed on an interior wall, away from direct sunlight, drafts, and not directly above a baseboard heater.
• Seal wall opening: Remove the thermostat and use foam or putty to seal large gaps in the wall box that may allow cold or hot air to affect the sensor.
• Adjust settings: In the Mysa app, enable any available adaptive or proportional control modes and verify the correct heater type is selected.
• Verify temperature calibration: If supported, use the app to apply a small calibration offset after comparing with a reliable thermometer.

If overshoot persists despite proper placement and settings, the internal sensor or control algorithm may be out of spec. Replacement may be considered.
