The room temperature overshoots the setpoint by several degrees before the system shuts off.

Safety: No electrical hazards. Adjustments are in software and placement.

• Step 1 – Check thermostat location: Ensure the Ecobee is not directly above a supply vent, radiator, or in direct sunlight. If it is, consider relocating it.
• Step 2 – Adjust thresholds: In Installation Settings > Thresholds, fine-tune the heat and cool differentials and temperature correction to reduce overshoot.
• Step 3 – Use room averaging: If you have SmartSensors, enable room averaging so the thermostat uses multiple readings instead of just the base unit.
• Step 4 – Verify sensor accuracy: Compare Ecobee’s reading to a reliable thermometer. If consistently off, apply a temperature correction in the settings or replace the thermostat if the error is extreme.
