You can use any automation system to accomplish what you want for swg with any brand swg so long as you have one additional relay available. Just take power from the load side of the pump relay to supply power to the line side of the swg relay. Set the swg relay schedule as desired.
This is exactly what I had been planning for a SWCG with regard to mains power to match to pump status. However, I am confused that you state you need 1 additional relay. is this a high voltage relay or a programing aux. relay? The SWCG is connected to the load side filter pump high voltage relay so just trying to understand the comment about another relay. Thanks.

. For me, I think it's very likely that one day I would set the timer incorrectly but it actually takes more than this to fail..
I had a timer mishap a few weeks ago, albeit on my LC injection, I was changing the injection time and didn't enable the stop time. Dumped about 7 gallons of LC IN the pool.

Sorry for the delay in getting back to you. The extra relay is only required if you want to set your to run It's a shorter time than the pump runs. I do not believe the extra Power supply from your pump has a timer function . If you want the SWG to run anytime anytime your pump is running then you do not need the extra relay..

I hope this is helpful.

I have a VS pump and a SWG. The SWG is on a timer. The pump uses the onboard programming. SWG requires 1400 rpm to trip the flow switch. Pump runs 1600 from 8 to 5 for skimming an chlorination, and 1000 the rest of 24/7, (which cost near nothing on my electric bill, and is probably better for the pump than stopping/starting). SWG timer is set for 8:30-4:30.
If the timer should fail or ever get out of sync, the flow switch is secondary backup. If both timer and flow switch fail, guess what…The pump is still running (albeit at 1000rpm). That is three levels of safety, and probably much less prone to any issues than any current sensing relay.

Yup, I did. The current sensing device I use is a CR4395-EH-120-110-X-CD-ELR-I.
The current trip point is adjustable between 0 and 10 amps, however, I reduce this range to 0 to 3.3 amps by looping the 220V line through the transformer 3 times.
The part you referenced is a 1-10 volt. Was the 0-10 a mistake...or did I miss something. Thanks.
