Youtube it. I have this controller. The top display is the cycle timer. So many minutes on so many off. I don't use it myself. I have other cycle timers on my pumps.
The other two are temperature control and humidity.
Look up the unit on Hydrofarm.com. They have a pdf file of the owner's manual.
Hey @Mykotik, I don't have one but I looked at them a lot. They should be pretty simple, maybe. lol It should have a temp sensor and a humidity sensor. You'll have a high and low limit that you'll program in for temp and humidity. But I don't know if it will do a day and night cycle though. I'd plug it in and play with it. It's not as techy as you might think, and I'm not a techy guy! lol But just scroll through the functions and see which plugs become live. Just another piece of the cannabis jig-saw puzzle. lol Good luck man, post your findings as a review. 👍

thanks all. Will do I am still trying to figure it out setting wise lol …maybe dad got it for me as a gift so I had to make use of it
It has a day and night cycle for temperature and humidity. Push the button in till it clicks. Adjust temp or humidity and push again to set.
I've only had to mess with it a few times but it's so long ago I can't remember. Lol
