🧠 How to Use

Install your Cloudline Pro S at the start or middle of your ducting run for optimal ventilation control.

💡 Note: The Cloudline Pro S series uses the exact same fan hardware as the T series—the only difference is the controller. The T series comes bundled with the Controller 69 Pro, while the S series includes a basic 10-speed controller and gives you the flexibility to upgrade. Plug in the wired controller to dial in the airflow. To unlock smart automation features, pair with Controller 69 Pro or Controller AI+ and manage climate conditions via the AC Infinity app. For more automation, upgrade to a UIS smart controller for temperature, humidity, and scheduling features.
