Gavita Master Controller – EL1F Gen 2 (UK)

Gavita Master Controller – EL1F Gen 2 (UK)


With the EL1F you can control up to 80 lights in 1 room with 1 EC Fan and 1 Temperature controller. To control 2 rooms you will need the EL2F or 2 x EL1F controllers.

The ELF 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

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.

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.
