Aqua Rite SWG and Variable Speed Pump

[moragapool]

Hi, I am installing a new Pentair Intelliflow VSP. I have also have a Aqua Rite Salt Water Generator. Previously, I had my old single speed pump and SWG connected to a manual timer. The timer is broken and I would like to connect the SWG using a Power Sensing Relay. Note all of my equipment is wired 220V. After reading about this set up in other posts it appears the solutions is to buy one on Amazon ([FONT=&quot]CR Magnetics CR4395-EH-240-110-X-CD-ELR-I Current Sensing Relay with Internal Transformer, 240 VAC, Energized on High Trip, 1 - 10 AAC Trip Range). Another poster commented that he also installed the following: Enclosed Power Relay, 6 Pn, 240VAC, DSPT-NO in addition to the CSR. I do not really understand the difference between the two and why you would use them in combination with one-another.

I would appreciate some guidance here in addition to understanding how to wire them appropriately.

Thank you,

John,

The CR4395 only has one set of contacts.. So you can only use it to power a 120 volt SWCG... If the SWCG is run off of 240 volts you need to be able to break both L1 and L2.. You could do this by using the additional relay.

Thanks,

Jim R.

I’m pretty sure the SWG can be wired for 110 or 220 by simply moving a jumper wire in the control box.

Thank you guys. that helps. I am going to try it and let you know what I learn. I am hoping the wiring is fairly straight forward since I am new to this type of configuration.

I went through this same scenario last year when I installed my two pentair VS pumps. I wound up just leaving the Aqua Rite SWG on the timer. Just make sure the timer trips on during the hours of pump use. You don't want the SWG powered up without the pump on even though the flow switch would provide a safety net.

I did the same. I just moved the pump to the “hot” (supply) side of the timer and left my SWG on the switched side. Now the VS pump has power at all times and the timer is set to operate the SWG during a period that the pump is set to run.

My timer was broken so rather than replace the timer I have ordered the suggested parts from Amazon. I am looking forward to testing it out.

Definitely the more sophisticated solution, but I run my pump more hours than my SWG and sometimes at a speed too low to support the SWG. So, at least for my application, the less elegant old mechanical timer works better.
