I'm building a Biocube 32 for my Daughter and Grandson. I am trying to use 2 apex 0-10v outputs to control 2 Jebao SW-4's. No such luck. It seems like when I output voltage the pumps change speed but when I remove the voltage the pumps don't shut off. It's like they revert back to the Jebao controller settings. The instructions are terrible and do not include the setup of the o-10v input. I need some help setting this up. Hopefully it's something simple.
