Comes with a male-male cable (pack 8) - this make it ready to plug in to any GAS EC Fan. Instructions here The G.A.S EC1 Controller is a thermostatic fan speed adjuster that is perfect for outtake EC fans. There are 3 dials on the front of the unit that allow you to set various parameters. Set the desired temperature and fan speed will rise and fall to keep things comfortable. The other 2 dials set the maximum and minimum speed you wish your fans to run at. This way you can be sure there is always enough air flow and the controller will operate within these parameters. The G.A.S EC1 Controller must be used with Active Cables to operate properly. Plugs directly onto Systemair's EC fan range and draws power from them, meaning it doesn't need to be plugged into another power source! How the GAS EC1 Thermostatic Speed Controller Works Simply set the temperature dial to your preferred setting and the EC1 will adjust fan outputs to match your grow room heat levels. The EC1 also features an LED that indicates that grow room temperatures are higher than those set on the device, allowing you to adjust your minimum and maximum fan speeds, if necessary. The GAS EC1 plugs directly into any fans in the Systemair range that feature active cables (Systemair EC cables using white connectors). These active cables power the device, so there’s no need for a separate power supply. The EC1 can be combined with the Active Y-Splitter cable to connect two EC fans at the same. If you’re running intake and extraction together, just make sure that your intake fan is a size smaller than your extraction fan, as this will maintain negative pressure, preventing smells from escaping from your grow room.
