Replaced a one speed pump with a new Tristar two speed. Connected 'L1' to the pump load on the Pro Logic and 'L2' to AUX1. The 'A' was connected to the common of both the pump and Aux1. Ground was also connected. I then set up the Pro Logic as a two speed pump.

Since I've never had a two speed pump I don't know how loud the pump should be. I can't tell a difference in sound from hi and lo. I also cannot get it to prime. Did I wire something wrong or anyone have any other ideas? Bad pump? Thanks
