The LT 84-U wall-mounted switch gives occupants direct control over automated windows and ventilation, making it easy to introduce fresh air whenever it’s needed. By allowing users to actively support airflow, it helps buildings “breathe” more effectively—reducing stale air, improving comfort, and contributing to a healthier indoor environment.
