I have a Hayward Tri-Star 2 speed pump and just purchased an Intermatic T104R. After doing more research I see I should have ordered the T10604R. I assume this because you have to have a controller for each speed. From what I am reading it is most efficient to run the pump on low all of the time with the exception of cleaning tools attached to the skimmer. Could I just get by with the 104 then and manually switch to high speed when cleaning the pool?
