PMUP2 not seen in fusion, doesn't pump water. I have plugged it into the EB8 the Fmm module. no where will it been seen by fusion. Am I doing something wrong?
I will say the very first time I plugged it into EB8, the Apex lost all modules and I had to unplug all modules FMM PM1 and all 3 DOS units.
All Modules are back online but the PMUP still does not run.

I am certainly not an expert, but I own an Apex system, although I have not had a problem with the PMUP2. Recently I had one of my DOS fail and it was because the USB cable had become corroded. I switched to a link connection, which protects the connectors and the problem was fixed. Hope this helps.

PMUP is wired with a link plug from the factory, it does not use USB. Thanks for the advise and knowledge on the USB.

I believe I found it, there is a switch labeled LinkA or LinkB that has to be brought down to the dashboard in order for the pump to be turned on.
My stupidity, I'll test it when I get home from work and update this thread.

That was it. Need linkB switched moved to dashboard then take off auto as its set to fallback off.
