Hello,

I have a small pool/spa combo (11700 gallons) that has a Jandy FloPro VS 2.7 that I need to replace. I've learned that Jandy only wants to sell through their dealer network so I'm looking for options as I prefer to do the work myself to save a significant amount of money. I'm also starting to think that pump is WAY too big for my little pool based on my research so if I can downsize and save even more money, great.

The main thing I'm struggling with is confirming what other pump brands, if any, will work with my existing control board which is a Jandy AquaLink RS (no other model number anywhere on the box that I can find) but I'm not having much luck.

Any guidance or suggestions would be much appreciated. Thank you.

It is important to understand what automation model you have because AquaLink only works with Jandy and with Pentair, but that is dependent on what level of automation you have now.
A variable speed pump allows the system to work at a lower rpm (lower HP and lower energy usage) so don't be weary of the 2.7HP rating. The Jandy ePump has worked well for many. However it would be best to know what type of automation system you have to ensure what other pumps may be compatible.
Please read Jandy Aqualink RS - Further Reading
to determine the revision of your software also post some pictures of your AquaLink box.
 
Thanks for the response. I'm aware that the 2.7hp running a slower speed means It's not too much pump, but why pay for a 2.7hp pump when a 1.5hp pump will work? That's the point I'm struggling with.IMG_0148.jpegIMG_0154.jpegIMG_0155.jpegIMG_0156.jpeg

Others have been able to get the VGreen 165 working with the Aqualink see post below.

The Century (Regal-Beloit) VGreen variable speed motors have an RS-485 interface and the communication protocol has been identified as this pdf attachment which was posted in other threads. @MSchutzer Identified it as being correct at least as far as being able to read status and write...

For a given flow rate the higher HP pump will use less electrical energy than the lower HP pump.

So the higher HP pump will have greater efficiency and save you money in your electrical bill. You need to run the numbers with your electrical rates and pump runtimes and see what works best for you.

The VGreen 165 1.65 HP motor is not a good replacement in his Jandy FloPro VS 2.7 pump. The 2.7 HP impreller will overload the 1.6 HP motor.

The VGreen 2.7 can be used if one can be found.

Ok, so that may explain why it's such a big motor in relation to the size of the pool.

What RPM do you run your spa jets at?

What RPM setting do you run your Jandy pump?

Not exactly sure what RPM the spa runs at, It's never occurred to me to look that up before. I run the pump in the 1800rpm range during the 'normal' circulation cycle.

Flow at 1800 RPM with a 2.7 pump will probably require around 2700 RPM with a 1.65 HP pump.

But we need to understand what maximum flows your setup needs, like for the spa jets.
 
I'm having trouble with the following from the Aqualink RS write up that was linked above:

Jandy Aqualink Installation Manual[8] section 3.2.7 describes how to connect a Pentair Intelliflo pump to the Aqualink.
While the Aqualink RS can control an Intelliflo VS pump it cannot control the VF functions of a VSF pump.

Does this mean it will work with the Intelliflo pump but only as a single speed pump? Seems contradictory to me. I'm not sure what VF means. Thanks in advance!

VF is variable flow and controlling the pump based on flow GPM rather then speed RPM.

All IntelliFlo pumps can control RPM. Some pumps can control by either RPM or GPM.

The Aqualink only controls the RPM feature of an IntelliFlo pump and cannot use the VF GPM controls of a pump.

Ahhhh, ok, I think I was starting to come to that realization while reading more about that pumps features. So if I'm correct the pump below would work for my situation, though it's a 3hp rather than 2.7 which it will be replacing. I certainly hope this pump will work as it gets outstanding reviews and is much more affordable than a Jandy FloPro VS 2.7.

The Aqualink will only control the VS RPM features of the 011056 pump. The Aqualink cannot access the VF GPM features.

Note that Pentair says the 011056 pump is now obsolete and may be difficult to find. If you can pickup one then do it. Otherwise look at the InetlliFlo3 pump.

3HP versus 2.7 HP makes no real difference.
