Aqua Link Issue: No ability to run Two-Speed Jandy Pump on Low?

panamax53 · Aug 14, 2021

I am asking this for a friend whose pool builder here in Miami has told her that her aqualink system can only run her two-speed Jandy pump on hi-speed. This is a recent build as of July 2021.That just does not seem right.
I, as you can see below in my profile, do not have automation. My swcg and heater will run on low-speed and that saves on the electric bill. I personally have received a lot of bogus information from pool stores and from the people who built my pool. There are properly trained, intelligent and customer oriented techs and dealers out there, but you have to hunt them down.
Can anyone confirm the accuracy of the statement from the builder?
Thank you.

Not without more information.

What Jandy pump does she have? What model Aqualink? How many relays in the Aqualink? What is connected to the relays?

A 2 speed pump will require 2 relays in the Aqualink. If she has an RS4 with only 4 relays there is a good chance all her relays are being used.

Now why the builder set her up with an Aqualink that is incompatible with her 2 speed pump, or why she didn't get a VS pump, is a different discussion about PB competence.

Have her check in here with details of her build and we can see what advice is appropriate.

I asked her to forward these pictures. Do they provide enough information for you? We're not sure about the "relays".
Thanks for trying to help out.

Still not enough information.

You have to open up the Aqualink and show the wiring.

And need a list of all the pool equipment and pics of the full equipment pad and pic of the motor data plate.

What equipment does she have on the Aqualink Aux buttons or controls?

See page 44 in https://www.jandy.com/-/media/zodiac/global/downloads/0748-91071/6594.pdf?force=1

The Aqualink needs to have Aux2 free...

S1 DIP #2 ON- AUX 2 Controls Low Speed of Filter Pump
Turn this switch ON if you want to control both speeds of a two-speed filter pump. With this switch on, the filter pump button on the AquaLink® RS control panel will control high speed and the AUX\ 2 button will control low speed.

Here's the panel, motherboard and pump data plate.

Pad Photos Part 2.
Remember the profile data is not mine. She hasn't gotten around to loading up her total specs into a profile. I do have her using the app to maintain the pool which is going well for now.

She has a low budget system where a lot of costs have been cut in the equipment.

She has a 4 relay Aqualink RS without a Load Center.

It looks like she has one relay, AUX3, that is not used.

As I noted in post #4, AUX2 is used for the LOW SPEED control. What is connected to AUX2 should be moved to AUX3. Then an additional wire needs to be pulled from the pump to the Aqualink panel to connect to AUX2. And Dip switch 2 needs to be flipped on.

AUX2 and 3 can be swapped either by rewiring at the relay connections or changing which relay socket it is plugged into.

Allen,
That was a great response to my inquiry on behalf of a friend. We are both "challenged" when it comes to matters electrical and have learned a bit thanks to you.
Thank you very much!
I have a totally manual system and am happy with it. Adding an acid feeder via stenner pump really helped simplify matters to the extent I required. I find myself frequently playing around with the skimmer valve, main drain valve and pool cleaner valve depending on what needs to be done. It seemed to me it would be advantageous for my friend to automate those functions as well.
Is it possible for those to also be automated?
Is her plumbing properly designed to allow for that?
If possible that would require a different and more expensive unit with more relays, right?
Thanks again,
Max

I said she has a low budget system where a lot of costs have been cut in the equipment. She has a lot of ball valves that cannot be automated and will start sticking and breaking in a few years.

I don’t know which pipes you want to automate and for what purpose. Explain what specifically you do manually that you want to press a button to do.

Looks like Aux 2 is not being used as a relay, but the line side of it is used to power the Aqualink. This is a waste of the relay and so the low speed can just be connected to Aux2. Also, I see the ground bar only has the ground coming in, but nothing else is grounded. That is probably not safe unless they are grounded some other way. There are connections for valve actuators which are already connected (presumably to switch between pool and spa mode).

AUX2 is switching 120V on the red wire. Probably the pool light.

There is nothing to ground with no CBs in the panel.

e_sully, thanks for piping in her with your comments too.

Allen,
I find myself often adjusting my suction cleaner and skimmer valves to increase surface skimming (my south Florida bug load is significant). When I 'm satisfied with the surface I'll readjust the skimmer ball valve back to 45 degrees to allow the suction cleaner to run properly. The suction cleaner, when running, requires the main drain valve to be closed. Once a week I like to flush my main drain and shear valves. In reality those valves get operated a lot more than spa valves in the typical home. It's so easy for me, I dont see any need for automation for myself, but I thought since my friend was ordering automation those functions might make sense for her.
Hope that cleared up my question.
Max

Since there are four relays then that means four items can be remotely controlled? The pump hi speed for one, low speed for two, lighting three and which one controls the two automatic valves for the spa?

e_sully · Aug 16, 2021

My mistake, didn't see the red wire (for some reason). Yes, probably the lights. Wouldn't the pump itself need to be grounded? My ground wire runs into the panel, but my panel includes a subpanel. Anyway, don't want to add confusion. The automatic valves don't use the relays, they are 24V and are the plugs at the top to the right.

She has a spa blower on AUX1.

The suction and return valve actuators are controlled by the SPA button and don’t use a high voltage relay.

panamax53 · Aug 17, 2021

So the solution would be to move the spa blower to the last relay on the right so the low speed could be then gon on Aux 1. Or could/should that blower or pool light be connected somewhere else?

Nope, the Aqualink needs to have Aux2 free...

Turn this switch ON if you want to control both speeds of a two-speed filter pump. With this switch on, the filter pump button on the AquaLink® RS control panel will control high speed and the AUX\ 2 button will control low speed.

Filter/Pump Relay - Pump
AUX1 - Spa Blower
AUX2 - light needs to be moved to AUX3. Then connect pump low speed to relay
AUX3 - becomes pool light

Got it!
Based on what you saw in the plumbing pictures would it be feasible to add an automated valve to the skimmer, cleaner and main drain lines?
According to E_sully above, the automated valves are low voltage 24v lines and get connected to the sockets above relays 2 and 3. It looks like there are 5 open sockets.
Does that mean 5 more valve actuators could be added?

No, the sockets are for specific functions...
