This controller is Bluetooth only. 

UIS Controller 69
  • A digital controller which manages up to four devices from fans to grow lights and provides each with its own independent programming.
  • Automate devices to dynamically change speed and brightness levels in response to temperature and humidity.
  • Additional programming includes grow cycles, scheduling, timers, minimum levels, and custom transitions.
  • Connect with our app via Bluetooth to unlock advanced programs, set alarms, and notifications, and view climate data.

A next-gen controller that connects with up to four different devices from fans to lights to provide each with independent climate and time-based programming. The backlit display reads the temperature in Fahrenheit or Celsius and can be switched off while programs run in the background. Built with a kickstand and includes hardware to be hung on walls. The 12-foot sensor probe with therm-alloy head accurately detects current temperature and humidity conditions.


Go beyond the basic on or off; trigger and set dynamic programs that adjust fan speed and light intensity in response to changing temperature and humidity. You can set minimum idle fan speeds that only increase when triggers are activated. Timer, cycle, and schedule modes add custom on-demand activation for a variety of indoor growing uses. Securely connect with the AC Infinity app via Bluetooth to remotely access your devices, unlock advance programs, set alarms, notifications, view historical charts, and export CSV data.

AC Infinity Cloudline S-series Fan 

The one and only. AC Infinity fans. Energy-efficient, quiet AF and value for money. These S-series come with an 8-speed manual controller 

  • Features an 8-speed manual controller utilizing PWM. See UIS Controllers for temperature and humidity controls.
  • Mixed flow design combined with a PWM-controlled EC-motor for a truly quiet and energy-efficient performance.
  • Kit also includes corded AC power adapter, installation manual, and all necessary mounting hardware.

Features an inline speed controller utilizing PWM (Pulse Width Modulation) technology. Contains an EC motor for a quiet and energy-efficient performance. The motor box containing the fan’s impeller and blades can be detached from the mounted frame for easy cleaning and maintenance. Complete kit includes one duct fan unit, one inline speed controller, installation manual, all necessary mounting hardware, and all necessary mounting hardware.


The inline speed controller enables you to set the duct fan’s speed to optimal noise and airflow levels for various environments. Unlike common AC-powered duct fans that suppresses voltage to control fan speeds, this duct fan features an EC-motor that is precisely controlled using PWM (Pulse Width Modulation).

This technology enables the fan's motor to be able to run smoothly at extremely low RPM speeds without generating motor noises and heat as seen on variable voltage controllers.

Eight-speed options are available with a power switch, and backup memory.
