Pentair Superflo VS connected to iAqualink RS 8

I recently had to upgrade my pump and went with the Superflo VS. The VS has it's own control for operations, so it simplified my life some, but I wanted to keep the ability to turn on the cleaner or hottub on demand (remotely) as I was able to do with the iAqualink and the old "dumb" single speed Pentair. So I bought the communication cable that the manual for the Superflo said to buy and wired it into the iAqualink per the manual here: https://www.doheny.com/media/Pdfs/74832-manual.pdf

Basically, the wiring was connect the ground wire (black) to ground, the red wire (5 volt) to the relay and then pick which speed you want to set the pump to from the other wires. I picked speed 1 and connected it to the relay. This worked for about a week and then the pump stopped responding to being "switched on" from the relay. In troubleshooting, I connected the "quick clean" and everything worked fine so I assumed I left it that way. Fast forward a month and I noticed that the relay is again not overridding the Pentair pump. It acts as if there is nothing coming over the cable.

Has anyone seen this before? Any suggestions? Any idea on how to test if it is the pump or the wire? What could be causing something that was working fine, to stop working suddenly?

Welcome to TFP.

Post pics of how you wired the relay in the Aqualink.

Do you have a multimeter? I would check if you have DC voltage between the red wire and any of the other wires.

I do have a multimeter and will check the DC voltage after work today. In the pic you can see the relay for "filter pump" the only thing I changed at install was to connect the com wires (red and off pink color), they are a little burned looking on the tip because I did not have a small enough wire stripper so I used the lighter and plier method....

What com wires do you have connected to the high voltage relay?

You have two devices connected on the LINE side of the relay and one device on the LOAD side. What are they? Which wires go to which device?

Ok, so I cleaned it up. Those were old wires capped off before I ever opened it. So I removed them. The black still connected, is jumping power from a relay to another, so I left it.

The pump control wire is getting 5 volt DC. The relay is turning on and off without issue.

The whole automation box is a mess with old and rewired things left behind. It needs emptied and restarted. My plan is to just warranty claim the pump and let them check it out. The pump works but the external control doesn't, so I am not hard down but hot tub season would be broken because I can't turn the pump on remotely and tie it to the heater properly.

Once the pump works right, I will just sit down and rewire the whole automation system.
