1) When Jandy phone support, Inyo Pools, and an Aqualink PDA dipswitch setting indicated I could control a 2 speed motor with my current panel, I ordered a new 2 speed motor and pump relay switch (#6796) for my failing Stealth single speed. Before taking my system apart I started to try to review the nature of Aqualink programming and TFP notes on such (I know - a little late to be doing my homework
). I ran across this:
"Oct 25, 2014
Question - Can I use a 2-speed pump with an older Jandy Aqualink?
Response - 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 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 the 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.
Does this mean there is no conditional programming - eg, "if the spa is turned on, the pump will be set to high" or "When cleaner turns off, filter pump returns to low speed"? Must everything be set by clock or else manually?
2) Also - Will my pump need to use 2 Jandy relays or will the motor relay switch (<Jandy Dual Speed Pump Relay Kit - 6796 - INYOPools.com>) serve that function?
