The EL1 has one output channel, and is best choice for use for one room without auxiliary equipment or alarm contacts.

If you require switched auxiliary equipment during lights on / off, alarm contacts and/or a 2 room 12/12 setup, the Gavita Master Controller EL2 is most suitable.

Lighting control at your fingertips! The Master controller EL1 and EL2 Gen 2 are our entry-level systems for centrally controlling large rooms with e-series fixtures. The second generation of Master controllers features improved and expanded functionality that raises the bar including non-volatile memory, event logging, independent sunrise and sunset settings and independent light cycles on the EL2. The EL1 has one lighting control channel and the EL2 has two lighting control channels. The EL1 can control 500 max repeater bus fixtures and 40 max single bus fixtures without a booster. The EL2 can control 1000 max repeater bus fixtures and 80 max single bus fixtures without a booster.

Gen 2 improvements

Memory – All master controllers use dependable, non-volatile memory to store user settings.

Logging – All master controllers now have logging functions for high/low temperature, last auto-dim event, last shutdown event and last power loss, including the event’s date and time

Separate sunrise/sunset control – Set different periods for sunrise and sunset

Independent cycles on EL2 models – These cycles let you program two different, overlapping cycles (for example, a 12/12 on channel 1 and an 18/6 on channel 2).

Independent programmable External Contactor Modules (ECMs) – In Gen 2 EL2 controllers, now you can choose whether they switch on or off and which channel they follow. The results? Flexible integration and automation.

Dimmable electronic ballasts have been around for many years now. They offer flexibility when you need lower light intensities, for example during the vegetative phase or when climate conditions are so extreme that a healthy climate is hard to maintain. Moreover, they can be boosted to optimize lamp performance and efficacy. Unfortunately, it is not always easy to adjust multiple ballasts or be there at the right moment when you need to dim your lights. Another problem is the high current that ballasts require when switched on at the same time (the inrush current). You need elaborate contactor equipped switchboxes to switch your ballasts on and off.

The Gavita Master controllers (in combination with suitable Gavita e-series ballasts, or Gavita Pro Complete Fixtures) offer a solution for all these issues, even with a cost reduction when you look at larger climate rooms. Our e-series ballasts no longer require a switchboard to be switched on and off, and no longer need their own switch to dim or boost them. Now you can just touch a few buttons on your controller to be in complete control of all your connected ballasts at once. Our Master controllers do this, and much more!

Available models

The Gavita EL controller series currently comprises of two models: The EL1 and EL2. Both feature auto-dim, auto-shutdown, sunrise/sunset and timer. The EL1 has one output channel, while the EL2 has 2 output channels and additional outputs for External Contactor Modules and alarm contacts. For one room without auxiliary equipment or alarm contacts, the EL1 is the best choice for you. If you require switched auxiliary equipment during lights on / off, alarm contacts and/or a 2 room 12/12 setup, the EL2 is most suitable.

Functionality overview

Easy installation

Installing the Master Controller is a breeze: it's a matter of plugging in, setting the dials of the ballasts to EXT (External control) and looping the low voltage control cord from the controller to your ballasts - all plug and play. Easy, safe and flexible.

Clear interface

The five language interface is intuitive to use with just 5 buttons. In plain text you see all settings, warnings and statuses. For an easy overview we have added LEDs for each output channel, which indicate whether the lights are on, dimming or shut down due to a dangerous high temperature. The indication LEDs are supported by a full text warning on the high quality green OLED display.

Replaces timers and contactors

You can plug your ballasts directly into mains outlets. You do not need any timers or contactor boxes any more: the ballasts are in stand-by mode and wake up when they get the signal from the controller. This means that you don't have any inrush any more when you switch on your ballasts. Just set the on/off time on the controller and you are good to go.

Dimming and boosting

Once you have connected your ballasts to the controller and set the on/off time you can set the output power centrally by the push of a few buttons. You can choose to have the output power displayed as a percentage or in actual output wattage of your ballasts. We even offer you a sunrise/sunset time setting in which the lamps ramp up or down at the start and end of the cycle. Autodim and safety shutdown based on room temperature. The Master controller is equipped with temperature sensors. Though we do not intend for you to use the Master controller as a climate controller, it can help you save your crop when temperatures in your room rise beyond your climate control capabilities. At a set temperature (normally a few degrees above your set ideal climate temperature) the Master controller will automatically dim your lamps, to prevent crop damage. In case of a complete ventilation failure or other calamity, when temperatures rise even more, the Master controller shuts down all connected equipment and activates the alarm contact.

Provides piece of mind but should've got an EL2 Review by Jarrett
Overall Rating
Works great! Enjoying the reliability and ease of install...but I should have read it more carefully before ordering. Thought the EL1 was the same as the EL2 only it controlled up to 40 lights/ballasts. I didn't realize the EL1 wouldn't control my CO2 or humidifier. Reading is fundamental (Posted on 6/19/2015)

Works as advertised and everything the other guy said is true. This thing is functions perfectly as advertised.

However you will immediately regret purchasing this one when you realize that it doesn't come with even a sliver of all the bells and whistles the EL2 comes with. Don't waste your time with the second best gavita controller on the market. Just ask your mom for some more money and just get the EL2 right away or you are gonna have a 300 dollar coaster because this thing looks pretty useless next to the EL2.

Don't have buyers regret. for 50 bucks more you can do way more and future proof your garden.

Lovin' my Master Controller!! Review by Jason
Overall Rating
Sun up? Check. Sun down? Check. Automated controls capable of decreasing light output (and even shutting down entirely) when temperatures reach specified levels, thus ensuring I don't burn my crop before I burn my crop? Check. Mmmm......this thing is more reliable than my wife!! And she's a gem (wife, that is)!!!

The sun up/sun down function has REALLY helps the plants ramp up/down....kind of like in nature.....which has had a visible effect on my plants, and it's only been a month since I implemented this new setup. Already visible increase in production levels. If you get any of the Gavita e-series lamps, make sure to get one of these to go with it!! A very worthwhile investment for any serious grower.
