Hello, I have a question, I have the Ice Cap 4K and I wanted to know if I can control (Turn OFF/ON/AUTO) the IceCap 4K Pumps using the 3.5mm stereo jack plugged into the Icecap cable and the other end into the Apex Port. Not sure I am doing this right, once I plug the cables in and try to turn OFF the switch on the Apex, the pumps are STILL running. I also checked in the Hydros App via the options panel, and have the Mode Control selected (0-10V Input 1)
