So if you ask anyone who knows me, they will tell you that I have a problem. Well.. depending on who you ask, they may tell you I have many problems. That's neither here nor there, if I'm being honest. Anyway, one of my big ones is my inability to leave well enough alone. I mentioned earlier today that my new VSP arrived. After work I took it out of the box and gave it a good once over, and while I was doing that I noticed "huh.. that pump housing looks AWFULLY similar to my old Stealth. In fact, I'm like 99% confident it is. I bet I could just undo the unions on the old pump and slide this one right in." Well, I took some quick measurements of my old pump and determined, yes, in fact, the housing is either identical or VERY, very similar. So what else kind of project do you start at 6 in the evening? Install a new pool pump of course!
I shut the power off to the pad, removed the electrical connectors, loosened the unions and took the old pump out of the way. After a bit of finagling with some shims (these will go away when I redo the plumbing on the pad to accommodate the SWCG and install the heater properly with a bypass. the pad has sunk over time a little bit due to shifting soil around the house. ask my foundation about that), connecting up the electrical, and running a new wire for the RS-485, I was ready to power things up. I turn the breakers back on, the Aqualink boots up aaaaand.. nothing. Huh. OK.
The manual says something about going into the settings on the controller and selecting "VSP Setup". Alright, scroll through the good ol' All Button.. well boss, there's nothing about VSPs in here. The AL PCB has almost the latest software (V is most recent, 9/2022 for what it's worth), so I KNOW it knows what a variable speed pump is. Jandy woudn't REALLY give you no way to control a VSP would they? Sure they would. They're Jandy. I hate them.
I head over to the Wiki, and my favorite article, Aqualink RS Further Reading. What does that article say?
You need to have iAqualink or the OneTouch controller to setup a VS pump. The All Button controller cannot do RS-485 control for a VS pump.
Excellent. Good stuff. Fortunately, I
already went through this nonsense a year ago when I first moved in this house. Dig out the old car tuning laptop I have all the Aqualink sim stuff on, plug it into the Aqualink PCB, fire up the Aqualink Touch simulator which simulates the relatively unknown Aqualink RS Touch controller, and boom. I set up the VSP speeds, hit the pump filter button and boom, the pump whirrs to life.
I can't believe how quiet this pump is. Why did I wait so long to replace that old rubbish single speed pump? This thing is awesome.
For now just to test things out and shake it down, I basically have it running 24 hours a day at 1750 RPM, only spinning up for the cleaner, spillover, and spa. Even running all day long it'll cost less than my old 2 HP single speed running 8 hours, which is what I had it set on over the summer. That's insane. I'm actually kinda excited to get the SWCG in and running whenever it arrives. I'm ready for summer now.
