Introduction
Welcome to the AC Infinity UIS™ platform — the most advanced and versatile climate and environment control ecosystem in the world! Choose from a constantly growing selection of devices that work together to create your ideal environment. Connect up to eight devices to the Controller AI+ and program each one individually, tailored to your application. Our innovative system can precisely control each device's output from 0 to 10 — such as fan speed or light intensity — to achieve exactly the climate you want.

Quick Start

- Plug the power supply into the bottom of the controller, then into an outlet.
- Connect the temperature/humidity/VPD sensor to the designated port on the bottom of the controller.
- Connect your first UIS device to one of the eight ports on the bottom of the controller.
- Press the "Port" button until you select the port your device is connected to. (See diagram below.)
- Press the "Mode" button until you select the desired program for your device. (See mode info below.)
- Use the "Up/Down" buttons to adjust the mode's parameters. The program starts automatically.
- If needed, check settings that may affect your program. Then return to the desired mode.
- Connect additional UIS devices as needed and repeat steps 3 through 6.
