  • Page 7: Introduction

    Introduction 1.1. Product description The Gavita Master controller EL2 is a dual channel controller which can control up to 80 ballasts/lights in climate rooms. Unlike a switchboard, which switches the power supply of regular ballasts on and off, the controller can control appropriate Gavita e-series ballasts by means of a low voltage control signal.

    4.2. Installing and connecting the temperature sensor(s) Warning! The Gavita Master controller is not a climate controller. Do not use the product to manage the temperature in your climate room. Caution! Only use Gavita temperature sensors. Caution! Ensure the controller measures the same temperature as the climate control system (see paragraph 5.2).

  • Page 16: Installing The Temperature Sensor In "Follow Mode" (One Room)

    Installing the temperature sensor in “Follow mode” (one room) 4.2.1. Only one of the provided temperature sensors is needed in “Follow mode”. • Place the provided temperature sensor as close as possible to the sensor of the existing climate control system, so both sensors will measure the same temperature (4A) •...

  • Page 17: Installing The Temperature Sensors In "Inverse Mode" (Two Rooms)

    Installing the temperature sensors in “Inverse mode” (two rooms) 4.2.2. Two temperature sensors are needed in “Inverse mode”. • Before placing the temperature sensors, determine which controller channel (main/aux) controls the lights in which room (“main” room/“aux” room) (5) • Place one temperature sensor in each room.

    4.6. Connecting the controller to the mains Warning! When you power on the controller, the connected ballasts may ignite. Either: a) make sure your ballasts are not connected to mains yet or b) the signal cable of the ballasts is not inserted in the controller yet before connecting and programming the controller.

  • Page 27: Preparations Before Use

    Preparations before use Caution! Set the controllers output mode to “OFF” (see paragraph 6.6.) to ensure no ballasts will be accidentally activated during the controller setup. After this it is safe to either connect the ballasts to mains or insert the signal cable to the ballasts into the controller.
