Let me re-try this post:
For anyone interested I purchased the Jandy FloPro. Here's some observations. My equipment is almost 100' away from the skimmer and the solar heating is 30' up on the 2nd story roof.
I'm using the Jandy supplied JEP-R controller with old 2005 Aqualink RS system. It took a few hours to get everything to function how I wanted, but saved $500 for now on the iAqualink, maybe next year.
I have speed 1 set at 1250 for regular turnover, with speed 2 set to 2350rpm for the solar. The remainder of the settings are manual, so speed 3 is set for 2500rpm for the navigator which I now only use once a week for a couple of hours when I am at home (previously it ran permanently).
Slowest adequate skimmer speed = 1250rpm = 150 watts approx. 30 GPM, 9 hours run time (could probably drop a few more RPM, but not much to be gained)
Slowest adequate navigator speed = 2500rpm = 800 watts approx. 45 GPM, use 1-2hr per week
Slowest adequate skimmer + solar = 2350rpm = 650 watts approx. 40 GPM
Electricity bill dropped from $120 to $45 first month (Southern California)! Will increase over the summer as I use more solar.
GPM are estimates from 5 gal bucket spillway measurement over 1 min (don't flame me).
Notes
To use the solar, may have to experiment with the primer time, mine is set at 5 minutes, turn the solar valves first (mine are all JVAs connected to One Touch), then 2 minutes later start the 2nd speed.
Power is only applied to the pump when the RS system requests the pump to run. So the JEP-R loses it's clock memory (think VCR flashing 12:00) each time the RS turns the pump off. Fortunately JEP-R does not forget it's timer settings.
Option 1 is to leave power permanently applied and use the JEP-R to control everything.
Option 2 (my choice) use the RS (One Touch) to control everything as normal, set the JEP-R to power the pump on at 12:01am (so one minute after the RS applies power) and then run for 9 hours. Set RS to turn off the pump 9 hours 2 minutes after asking it to turn on. Set the solar to come on/off through the RS, so have to sync RS & JEP timers for this event also. I set the solar to come on after 3 hours, and 2 minutes later the JEP-R timer 2 kicks in to the higher speed. The prime time runs for 5 mins at 2750 RPM (1100 watts) sufficient to circulate to the roof and back down, then the system kicks back down to 2350rpm. The solar kicks off after 3 hours and the JEP-R is sync'ed to drop down to speed/timer 1.
Hope that helps anyone with the similar questions regarding variable speed pumps (Jandy FloPro) with older Aqualink RS.
