The EL F controllers are new to the family. Not only do they offer everything the Gen 2 controller has to offer in control and safety, but they also provide integrated, intelligent fan control, based on a PID algorithm:

- 0-10V EC fan control
- Intelligent PID fan control
- Non-volatile memory
- Event logging
- Independent sunrise and sunset settings
- Independent light cycles on the EL2

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.

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

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!

Simple programming

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

Intelligent PID fan control

PID stands for Proportional, Integral, Derivative. It is a control algorithm which is used in industrial control processes to provide the most accurate and stable process temperatures and flows. The PID control reduces oscillation and is self-learning, based on continuously measuring the effect of any changes in temperature and fan speed. The result is an absolute stable temperature in your grow room and a quiet fan.


Logging functions for high/low temperature, last autodim event, last shutdown event and last power loss.

Separate sunrise/sunset

Set different times for sunrise and sunset.

Easy installation

The complete installation is plug-and-play. Every e-series fixture comes with all necessary cables to install it on the e-series control bus.

Crop safety - autodim

In extreme conditions the Master Controller automatically dims your lights, so your plants will survive the high heat.

Crop protection – auto-shutdown

When cooling or ventilation fails, the Master Controller automatically switches off your lights, preventing imminent damage to your crop (or worse).


Nonvolatile memory to store user settings.

Independent programmable ECMs (External Contactor Modules)

The ECMs (External Contactor Modules) are used to switch on or off auxiliary equipment during the lights-on or lights-off period. In the GEN2 EL2 controllers you can now choose whether they switch on or off, and which channel they should follow. This allows for flexible integration and automation.
