HI just installed the Hayward HP21404T heat pump and found I have to run the variable speed motor at 3150 rpm or the heat shuts down and reads HP. Any idea why this is?

The heat pump is not receiving enough flow on the lower speeds. That is why it won't work unless it's at 3150 rpm. 

Sometimes the cause of this issue is a dirty filter. Try cleaning the filter and then run the pump on lower speeds to see if the heat pump will work.
