Beschreibung
Zusammenfassung:	A system includes a controller, a heating, ventilation, and air conditioning (HVAC) unit, first and second dampers, and first and second pressure sensors. The first damper is positioned at a first air duct that supplies air from an exterior of a premises. The second damper is positioned at a second air duct that supplies air from an interior of the premises. The first pressure sensor is configured to detect an air pressure exterior to the premises. The second pressure sensor is configured to detect an air pressure within the premises. The controller is configured to receive the detected exterior air pressure and the detected interior air pressure, and the controller is configured to change the air pressure within the premises by adjusting at least one of the first damper and the second damper based on the detected exterior and interior air pressures.
