Product Description

The Gavita EL3 Master Controller is a professional lighting management system designed to simplify control of large Gavita lighting installations.

Instead of manually managing individual fixtures, the EL3 allows compatible e-Series lights to be organized into two lighting zones and controlled from a single touchscreen interface.

Growers can create lighting schedules, adjust intensity, configure sunrise and sunset periods, and establish temperature-based protection settings.

This makes the EL3 particularly useful for cultivation facilities where consistent lighting schedules and automated protection are important.

Control Up to 512 Gavita Fixtures

The EL3 can control up to 512 compatible e-Series fixtures, with a maximum of 256 fixtures per zone. This provides substantial capacity for large cultivation rooms and commercial installations. (Gavita)

The two-zone design allows growers to configure separate lighting areas and schedules within the same controlled system.

This can be particularly useful when different sections of a facility require different lighting programs.

Programmable Lighting Schedules

The EL3 allows growers to create complete lighting schedules for different stages of plant production.

Program lighting from early vegetative growth through flowering while maintaining consistent daily cycles.

Features include:

• Programmable on/off times
• Adjustable light intensity
• Sunrise simulation
• Sunset simulation
• Separate zone control
• Temperature-based dimming
• Temperature-based shutdown

The result is a centralized lighting system that can automate daily lighting changes without relying on multiple independent timers.

Automatic Temperature Protection

One of the most useful features of the EL3 is its ability to respond to high-temperature conditions.

Growers can establish temperature thresholds that automatically reduce light intensity when temperatures rise beyond the selected setpoint.

A higher temperature threshold can also be configured to shut down compatible lighting when additional protection is required.

An audible alarm can be activated when programmed conditions are exceeded. (Gavita)

This provides an additional layer of protection for lighting systems and the growing environment.

Environmental Monitoring and Data Logging

The EL3 can work with compatible Titan Controls sensors to collect additional environmental information.

Depending on the sensor configuration, the system can log information including:

• Temperature
• Humidity
• CO2
• EC
• VWC
• Substrate temperature
• Lighting cycles

This historical information can help growers review environmental trends and evaluate growing-room conditions over time.

Compatible sensors are sold separately. (Gavita)

Data Logging for Better Grow-Room Management

The EL3 includes data-logging capabilities that allow growers to review historical information collected by the controller and compatible sensors.

This can be valuable when troubleshooting environmental fluctuations, reviewing lighting performance, or comparing conditions between different periods of a crop.

The current EL3 firmware also includes improvements to data download and extraction, making recorded information easier to review and analyze. (Gavita)

Spray Protection Feature

The EL3 includes a dedicated spray function designed to temporarily reduce light intensity during spray applications.

When activated, compatible fixtures can be dimmed to 50%, helping reduce the potential for excessive light exposure during foliar spray applications.

This feature is accessible directly through the EL3 interface. (Sylvane)

Updated Firmware and Virtual Zoning

Gavita continues to provide firmware updates for the EL3.

Current firmware version information from Gavita includes support for additional fixtures such as the Gavita CT 2000e and Pro RS 2400e V2, along with improvements to data management and virtual zoning.

Virtual zoning allows compatible Gen 3 fixtures to be grouped into customized zones for more precise control within a cultivation area. (Gavita)

Always verify fixture compatibility and firmware requirements before installation.
