I had a loss of supervision at 4:30 yesterday morning. Takeover zones. Any reason that may be?
Did this just occur after an extended period of the panel functioning? Have you recently made changes to the panel or takeover module?
The quickest troubleshooting suggesting is to power cycle the panel, unplug transformer first, then battery, then plug in battery, then transformer.
If the takeover module was powered on after the panel was (only really applicable if it was recently) I have seen some signal malfunctions occur.
