Add Light (0-10V)

Here is what you’ll need to get started:

• A HYDROS device with a 0-10V OUT port (X4, WaveEngine V1/V2)
• 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 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 / Edit 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

• Family: Variable Lights
• Used In Schedule: This is a list of all external Light Schedules used by this output.
• Level Range: This is the lowest and highest intensity HYDROS will run your light fixture.  
  
  TIP: Consider the Level Range a governor. When you set up a “Light Schedule” that operates at 1% to 100% intensity, but the level range is limited to 25% and 75%, 1% on the “Light Schedule” corresponds to the light operating at 25%. Similarly, 100% on the “Light Schedule” means the light physically runs at 75%. The “Light Schedule” intensity range falls within the Level Range here.
• Overheat Input: This allows you to select a temperature sensor. 
  • Overheat Temperature: This feature allows you to specify a maximum temperature at which the lights will automatically turn off.
• Device Count: Slide left to right to select the number of lights you want to attach to this output. 
  
  TIP: This is a simple and efficient method for creating a group of lights. When you choose multiple lights, they will all function as a single entity.
  • Output Device X: Select the location of the light. In this case, choose 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 (-)
  • Off Voltage: Select the voltage level that shuts down the fixture.
    
    TIP: When dealing with 0-10V systems, it’s important to note that a 0 voltage does not always mean the lights are off. Sometimes, the lights will shut off at a voltage higher than 0. For instance, if your light stays on at 1.5V but turns off at 1.4V, then you should set the “Off Voltage” to 1.4V.
  • On Voltage: Select the maximum voltage level for your light fixture.
    
    TIP: Not all lights operate within the 0-10V range. Some manufacturers use different ranges such as 0-5V or 0-6.5V. It is best to contact the light’s manufacturer to find out the exact working range for your light.

Step 3: Save

• After configuring the output, tap the yellow bar at the bottom to upload your changes to the cloud and each HYDROS device.

Step 4: Create a Light Schedule

Now that you have created a Light Output create a Light Schedule ^[2] to run the light how you want it!
