Response to Thanks so much for your reply. I have a 10 year old Jandy Aqualink PDA system upgraded to a newer PDA but NOT the new board with the socketed CPU. The board schematic indicates a dip switch setting for a dual speed motor, and the Jandy parts rep said it could take a dual speed motor. 1)I am a bit confused since I don't see a service factor on my pump label. 2) Is a VS motor running at 1750 rpm more energy efficient than a dual speed motor running at the same speed? Thx, David
