Circupool and VS pump

[djdonte]

I currently have my RJ30+ wired to the mechanical timer on the same screws my 1.5hp single speed pump motor are hooked to. How would this work with a VS? The VS would have to be powered 24/7 and controlled by its own panel. Do I still need to have the SWG on a timer? Circupool says to just leave it on all the time and let the flow switch decide? Wont this cause extra wear of the control box?

The VS pumps typically have their own built in timer and so they get power 24x7 and shut on/off independent of separate timer. You should have the SWG on its own timer so you can fine tune the amount of on time it makes chlorine.

A separate issue that’s recommended is that you wire the SWG to only power on when the pump is actually moving water so that if there’s a bad flow switch that the machine doesn’t try and make chlorine. Without water movement, gas builds up until the system pops…

Check the pump for some kind of relay that gets switched on when it’s pumping.

I would be using the Pentair Whisperflo VS motor upgrade kit and there doesnt seem to be any type of relay or trigger wire.

If there’s no relay or trigger then just make sure the SWG and the pump are on the same breaker. Someone will probably chine in with a load sensing relay you can attach depending on your electrical skill level.

Hook your VS pump into 24/7 power at the timer and connect your SWG to the existing timer terminals. There are other options available including the current sending relay. I utilize a simple Wi-Fi switch to control my SWG. The advantage to a Wi-Fi solution is that it will sync to real time if there's a power outage.

One if the many benefits to running 24/7 (low RPM) is that i don't need timers. In the rare chance the pump shuts off but still has power (SWG shared on the breaker), then the flow switch does its job and kills the SWG. 99 out of 100 times if the pump shuts off, it's because the whole neighborhood lost power, including the SWG.

I recently made the same change. I connected the pump bypassing the timer and left the SWG on the timer. I have since added current detection so that the SWG isn't powered up if the pump isn't actually running.

Detecting if a pump is actually running?
