AC1 Fan Controller


The AC1 fan controller has two modes to ensure you can maintain a perfect environment. Either set fan speed manually, or control thermostatically.

  • Mode 1 – when the temperature probe is connected, the controller will thermostatically control your grow room environment
  • Mode 2 – when the temperature probe is disconnected, the controller will run at minimum set speed


The AC1 fan controller automatically increases and decreases the fan speed to maintain your set temperature.
When at or below set temperature, the controller maintains your minimum speed.

A key feature of the new the AC1 is the built-in overload protection that monitors the controllers internal temperature. In the case of overload, the controller switches the fans to full speed, protecting your
equipment from overheating.
