Haku Posted July 23, 2019 Share Posted July 23, 2019 Just installed the loop and during filling the pump will not move the water once turned on. The RGB works fine but seems like there is no life in the pump. I checked the power.. reconnected it. Still nothing. I tried changing port 6 on the commander pro to port 5 still the same. Switched it back because it said to use port 6. Any tips would be appreciated. Maybe I'm just being stupid today.. Link to comment Share on other sites More sharing options...
Haku Posted July 23, 2019 Author Share Posted July 23, 2019 Turns out I am indeed stupid, having closed the top inlet port to not let air in.... jeezus... Link to comment Share on other sites More sharing options...
c-attack Posted July 23, 2019 Share Posted July 23, 2019 The default pump speed is a bit low for complex loops. If you are filling and not getting progress, pulling the pump tach/PWM wire from the Commander Pro will bring about an instant maximum speed and usually push things along.
