I'm not sure the best place to post this so I'll try it here.
I am building a glycol loop for 3 conicals with internal chillers. My thought was to use the 12v aquarium controllers (Willhi) to actuate a motorized ball valve to open and close glycol lines to individual fermenters. See the schematic below.
I wired it to a usb adapter (5V, 1A) and the Willhi lights up and seems to be working. I wired as shown below (which I think is correct) and I can't get the valve to actuate. I haven't worked with this stuff much and am hoping someone here can help me out. Cheers.
