Kessil Spectral controller

[ghostmarine1]

I am using a Kessil H80 for my refugium I have a Kessil spectral controller that I don’t really use but I would like to start using it again. Does anyone know how to program it to be off in the day and on at night? Any help would be appreciated

You'll have to use the 0-10v port and create a program. There might be a built in program in the controller that you can use and just modify the times.
0-10v control starts at the 18 minute mark.

Also, it's probably easier to just use a basic timer and set the light to your desired settings. This is how I use my 160 fuge light.

I guess I should have clarified it’s not the spectral controller x

I believe “grow” is 40% color on the basic controller. Just use the quick set program and adjust the intensity to (100%) and set your start and end times. It follows military time be default. It should follow your on/off times regardless if it goes past midnight.
But I’ll be honest, using a basic timer is all you need and you don’t have to run a cable and the power supply for the controller. But I completely understand that you have the piece of gear and want to use it.
