Obtain ultimate control using a Gavita Master controller to manage your e-series fixtures.

Simply connect the controller cables to the fixtures with the T-splitter which is included, program the fixture dials to EXT (external control) then finally connect the power to fixture and controller. Plug and play!

The controller uses it's internal timer to control the interconnected fixtures and is able to adjust them to suit your output level, climate or even to simulate sunrise/sunset. There is no need for expensive light timers/contactors and protects against current in-rush during light switch on.

  • Celsius or Fahrenheit and 24 hr/AM/PM

  • Emergency shut-down

  • Plug and play

  • CE certified

  • 3-year warranty

  • Ease of use, plug and play installation and safety.

Just connect the controller cables to the fixtures with the included T-splitter (see diagram), set the dials on the fixtures to EXT (External control), plug the controller and the fixtures directly into mains and you are set to go.

The controller can switch all the interconnected fixtures on and off with its internal timer, adjust them to your required output level (in percentage or exact output power) and even simulate sunrise and sunset to gradually adjust the climate in your grow room when your lights go on or off. This electronic controller replaces expensive lighting timers and contactors while preventing ballast current in-rush when switching on your lights.

Two very important features are the auto dim function and emergency shut-down. When the temperature in your grow room rises beyond the control level of your climate control your crop can be damaged beyond recovery. The temperature probe senses this and will automatically dim the lights to not overshoot your safe temperature, and maintain it. The display and warning LED indicate when this happens, and also indicate if this has happened while you were away so you can correct the problem. If for any reason your climate control completely fails and the temperature rises to unacceptable levels the system will perform an emergency shutdown of all connected equipment. The alarm contact of the controller can be connected to your alarm system for instant notification.
