Question: What is the purpose of the switch beside the thermostat labeled “Ventilation Fan”?
Answer: This switch controls the principal exhaust fan in your home, allowing you to manually enable or override it. When activated, the exhaust fan draws air from inside the home and expels it through the exterior via the wall return grills located throughout the house. Be mindful when using this switch, as manually overriding the exhaust system could prematurely alter the acclimatization of your home.
