Got home late last night and the electrician had been out sometime during the day. I have power to my house again! Yay! Unfortunately, what I'd asked for didn't actually happen and I only have 220v available. Right now I'm just happy to have electricity. I have to get the new equipment plumbed in and wired myself. I want to add a current sensing relay for the SWCG so it will not run if the pump isn't running. No automation, heaters, etc. just a variable speed pump and SWCG. Separate circuits for pump and SWCG. I have this current sensing relay Adjustable Current Sensing Relay: 240V AC, Adj 2.00 to 20.00A, SPDT, 10A @ 240V but I'm not sure exactly how to wire it since I have to run the SWCG on 220v. Do I need to add anything else? Help please! Thank you!
