WFCO error code Audible alarm (AC reverse polarity)
AC REVERSE POLARITY PROTECTION: the incoming AC neutral wire and hot (lead) wire are connected backwards at the power center. The alarm inside the enclosure sounds and keeps sounding until the AC wires are connected correctly. The 8500 product sheet lists the detection as optional.
What to check, and in what order, is in the app. A step-by-step flow walks this code with the pass/fail measurements, wiring schematics and procedures that go with it, and it works offline in the bay.
