I just had a new pool built, however the pool builder only does the pool/plumbing. I had to find my own electrician which I did, but he was several weeks out. That's when I decided that I could do it myself. I'm handy and have done electrical work before. Everything works great trough the aqualink RS except the Jandy ePump. I can hear the relay switch the pump on, but there doesn't seem to be any communication from the RS485 to tell it to turn on and the speed. I've read through some post on this forum and did the troubleshooting where you jumper the RS485 connector(1-3 and 2-4). The pump now comes on when I tell it to in the aqualink app. At this point I thought it must be the wire (22/4) that I bought at a big box hardware store. I swapped out the wire with no luck! I moved the RS485 connector from one location to another on the aqualink. No luck! Everything else works perfectly through the aqualink app. I've read the manuals again thinking that there must be a dip switch that I missed, but everything I read says you just plug it into the RS485 and it works. This newer model (VSSHP220DV2A) only has dip switches 3 and 4. It does NOT have dip switches 1 and 2. At this point I just don't know what to do! I would think moving the pump slider to "on" would turn the pump on. Is there some setup that I need to do in the app? Is there a dip switch I need to flip? All the troubleshooting I've done says one or the other has to be bad, but they both work just fine on their own. They just don't want to work together!
