I returned home to my tank and my Gyre XF280 was not working. The controller has only the blue power light on but the pump does not function. Both are plugged into channel A. However, when I plug them both into channel B the pump functions at full power but the controller does not function. Full power is way too much for me, so thus it is not useful. I have tried updating the firmware but when holding the circle on it during power up nothing happened. My corals aren't looking too happy... Anything is helpful. Thanks!
