Keep the air in your home fresh by bringing in air from outside.
Set up Smart Ventilation
Smart Ventilation uses outdoor temperature, air quality, and more to determine the best times and amount of ventilation for your home. If the outdoor air quality is poor, or the temperature is too hot or cold for your target indoor temperature, Smart Ventilation pauses your ventilation system.
Note: This feature is only available if you have a ventilation system and have correctly configured it for ventilation. If you don’t have a ventilation system, you will not see this option available in Settings.
