Features & Benefits
0-10V EC fan control
Modern EC fans contain a brushless DC motor, which is powered by a controllable electronic driver. They offer a great control range while maintaining power, torque, and static pressure, at much lower energy use. Though they are more expensive than the traditional AC fans, their precise speed control and torque maintenance result in a much better, and quieter control of air flow.

No longer do you need separate high-power speeds controllers to regulate your extraction and intake fans: This little intelligent controller can control them all, more precise, quieter and with a much better performance. Whether you want to move 1 cf/s or 1,000 cf/s: this controller can handle any size EC fan.

Switch, dim and boost centrally
Now you have complete control over the light cycle and the output of your fixtures from one single point. Never reach to a ballast again!

Independent cycles on EL2 models
With our first generation, the EL2 models had a “follow” or “inverse” function, allowing you to use the two ports for a large room, or two flowering rooms “flip/flopping” in a 12/12 cycle. This is still possible, but now you can program the two channels of an EL2 completely separate. You can program two different, and overlapping cycles, for example a 12/12 on channel 1 and an 18/2 on channel 2. Basically, you have the functionality of 2 EL1 controllers in one, plus the extra functionality of the ECMs and the alarm contacts on the EL2 series

Simple programming
Setting up the controller is a breeze, with a 5 language text interface in plain language on a high quality OLED display.
