Managing Hayward Ecostar Pump and Aqualink

[rustlerski]

I just realized that my main pump (Hayward Ecostar SP3400VSP) runs only a single speed shown on the pump display as 85.5%. This strikes me as higher and louder than necessary, and I'd like to figure out how to run the system more energy efficiently and more quietly. From my reading on here, it seems that if I drop the RPMs, I'll still need to make sure the flow is sufficient to run the heater and SWG.

I see that one way to take advantage of the VSP is to wire up to 3 additional free relays on the Aqualink board. I currently have one free which if I read correctly can get me a another two speed options controllable through the Aqualink.

The setting on the pump is also set to Relay Control.

With that background, I'd appreciate some input on the following:

(1) Given the existing setup, should the pump be set to Standalone/Hayward instead of Relay Control?

(2) If Standalone/Hayward is a viable option, can I just set it on Standalone and manually program the pump timers to run the pump schedule at whatever speed settings work best (in lieu of wiring up the relays for more speed settings through Aqualink on Relay Control mode)? I played around with this earlier today, and it seems so.

(3) I know every pool is different, but is there a good rough time/speed schedule to start from and then make adjustments as needed?

(4) There is a module screwed into the aqualink housing in with the relays, but it's not connected to anything at all. Any idea what this is?

Thank you very much!

Is the pump being powered off with the relay? Would need to see what else is connected to the "filter-pump" relay. With the right wiring, you could control two speed with what you have now.
#4 - That is a two-speed relay for a 2-speed pump.

Yes, the pump is being powered off with the relay.

The other wire connections on the filter pump relay appear to be the heater and swg.

After trying a few different settings, looks like the swg still generates with the pump down to 1000 rpm. Haven't tested below that yet.

I ran wires this afternoon between the aqualink board and the pump. I will wire up that one extra relay tonight or tomorrow.

Is there any way to use the two speed relay that's in there and unused? Or am I best just buying another 3 R0658100 modules?

Thanks again!

You could use that 2-speed relay if wired correctly. You will be switching low-voltage from the pump itself to various inputs in the control panel.

I decided to buy a couple jandy relay modules to keep things consistent.

I wonder if that 2 speed relay is from an prior pump or if it's related to the Jandy Stealth Booster pump but unused.

Thanks again.
