First I will just say that NO I do not own one of these nor have I seen one in person, however from the videos that I have seen in regards to the built in controller it appears to have several modes such as pulsing and timed reversing of the flow direction. not sure if that answers your concern or not. To me it appears to function in regards to control and modes the same as most controllable pumps.
