Just purchased and installed my new Maxspect Gyre XF-230 Pump & Controller unit and followed instructions to properly connect the pump to the controller BEFORE connecting the device to power. The pump now runs on high, and the controller has no visual/display showing on it. Just a black screen and I can't make any changes to settings on the device. I really need help :( I just got this device yesterday and was very excited, and my experience is terrible already...
