When I came in to my office to see my tanks I saw the alarm and checked my sump level. Again, the float sensor saved me but it dumped about 4 gallons of FW into my sump dropping my salinity to 1.024 and my skimmer overflowed. I removed the 4 gallons back to the appropriate level and noticed water started flowing again from the ATO container....I checked Fusion to see if the PMUP was ON and it was in AUTO but interestingly it stated it was in the OFF state. I checked the log. It appears the ATO PMUP turned on at 7:58am for 10 seconds. At 8:19am I got the Alarm. It looked to me like the logic told the PMUP to turn off but didn't actually turn it off the PMUP. I went to the FW tank and it sounded like it was on but when I pulled the pump the sound stopped so that was inconclusive. I don't think it possible for me to have a siphon, the output of the RODI line is 18 inches above the height of the PMUP, unless it floated up which I suppose is a possibility....strange problem.
Anyone seeing issues where the PMUP power sticks on?
Thanks!
