Add Light (0-10V)

Here is what you’ll need to get started:

• A light with a 0-10V Input
• A HYDROS 0-10V Quad Cable ^[1]

Step 1: Connect the Light to the HYDROS Control

1. Connect the GX12 end of the HYDROS 0-10V Quad Cable and connect it to the HYDROS Control 0-10V OUT port
2. Connect one of the 3.5mm ends of the HYDROS 0-10V Quad Cable to the 0-10 IN port on your light fixture.  Please remember the color of the 3.5mm jack, as you will need that in one of the steps below.

Step 2: Create the Variable Light Output

1. From the STATUS screen on your HYDROS app, top on the three horizontal dots to the right of the OUTPUTS label and select “Add New Output.”
2. Tap on the + symbol at the bottom right of the page
3. Type in the name of your new output and then tap “Create.”

Step 2: Configure your Variable Light

• Type: Select “Variable Light”
• Min Level: This is the lowest intensity the HYDROS will run your light fixture at.  
• Max Level: This is the maximum intensity the HYDOS will run your light fixture.
• Overheat Input: This lets you turn OFF the lights if your tank temperature gets too hot.
  • Overheat Temperature: You select the temperature where you want the controller to shut off the lights.
    
    TIP: To see a list of all inputs available on MULTIPLE devices, you must first create a Collective ^[2].  Otherwise, only inputs on the same device will show.
• Output Device: Select the location of the light.  In this case, select the 0-10V channel based on the color of the 3.5mm jack connected to your light fixture.
  TIP: The 0-10v cable has four different connectors.

  • BLACK = Direct Output 1
  • BROWN = Direct Output 2
  • RED = Direct Output 3
  • ORANGE = Direct Output 4

  For the DIYers, the 3.5mm Mono jack is wired the following:

  • Tip = 0-10V output (+)
  • Ring = unused
  • Sleeve = Ground (-)

Step 3: Save

• Upload your changes to the cloud 

Step 4: Create a Light Schedule

Now that you have created a Light Output, create a Light Schedule ^[3] to run the light the way you want it!
