I would like to replace my current pool pump with a new one pump that has at least two speeds. I currently have a WhisperFlo, model WFDS-28, 2HP, 1.1 Service Factor (serial 1-08-B02), In June 2015, I purchased a 7092 (JDY7092) - Jandy AquaLink RS Conversion Kit Pool/Spa Combo from your company and installed it (works great). I would like the new pump’s speeds to be able to be controlled by the AquaLink system. Of course I do not want to break the bank, so I do not believe I need all the bells and whistle, but a way to keep my water flowing at a reduced speed and cost. Thank you for your help.
Hello GTrill,
Automation systems do not really “communicate” with 2-speed pumps. A 2-speed pump runs by supplying power to either the low speed winding or the high speed winding. So many automation systems like you Aqualink system just need 2 relays. One is turned on for high speed and the other is turned on for low speed.
If you do not have a spare relay, you could look at the newer smaller VS pumps, like the Superflo Vs or Max-flo VS or SuperPump VS. These have built in speed controllers but still require an external timer for on/off operation. When they pump is turned on it will run at a higher speed (you set) for an amount of time you set, and then switch to a lower speed (you set) until the timer turns it off. There is a 3rd speed you can select manually, like for vacuuming or the spa.
The “gotchas” with these pumps is that the speed can NOT be controlled by the automation system. So if it was running on low and you turn the spa on, the pump will stay on low and you will have to manually turn up the pump speed. OR if you have solar, it can not automatically increase the pump speed when solar is needed.
InyoAlan,
Thank you for the quick response. Not sure I am liking the solutions you mentioned. What about the variable speed pumps you mentioned? With my controller, what would be my best option and how difficult worked it be for me to install myself? Thanks again.

Hello GTrill,
The Jandy E-Pump Variable Speed 2.0 HP Pump - VSSHP270AUT may be your best option. I would recommend contacting Jandy at 1-800-822-7933 and speaking with a representative. They would be the best option to reference other compatiable VS pumps that you would be looking to control with your automation system. They would also be able to suggest anything additional components you may need. Thank you for your question!
