I added a Neptune BOB to a PM1 module to stop an overflowing skimmer. Apex classic running SW 4.53. After pulling the unused tiles back down in Fusion I noticed that switch 5 and 6 keep cycling open and closed but nothing is connected to them. I unplugged the BOB and the switches keep cycling. I have no plans at this time to use those switches but would still like to know what is causing this. Any ideas?
