So I set up the Apex A3 controller a few months ago. This particular alarm goes off every hour. I thought it was the sensor on the Neptune ATO, indicating that it was being used to fill the tank, but the evaporation rate and the time of the alerts doesn’t make sense to me…or maybe it does, you tell me … please and thanks!
Also, When I go into the device on the dashboard … this is what I see. And I built my control board for form not functionality… it’s a pain to diagnose and disassemble…
