As the most recent fan controller to be added to the GAS range, the AC1 is an effective and simple way of controlling your AC fans. With two modes, this controller ensures you’re able to maintain the perfect growing environment. You can choose to either manually set the fan speed or control it thermostatically. One top feature of this new fan controller is its inbuilt overload protection which monitors the internal temperature of the controller. Should an overload be detected, the fans are switched automatically by the controller to their full speed so the equipment can be protected from overheating.
