Hvac mode commanded to fanOnly?

Anyone ever see these things go sideways and come up with an active setpoint (TempControlPt) of 256F?
Had a building recently that I suspect took a power glitch or something along those lines that really caused some problems. Its 3x Excel 10s, all but one had a 256F active setpoint even though occ setpoints where all normal. Also 5x Trane Intellipak units with LCI cards that went into emergency stop - comms failure. That's all that's on this lon trunk and all but one unit went bonkers. System has been running fine for a few years now, so outside of lighting, power issue not sure what to make of it.
Dug around in the intellipak manuals and I don't even see the fault they told me listed. Most of their com faults in the books name the specific module and are all auto reset.

They all look to be set for hvacAuto. That point wasn't even pulled into the Niagara database till I just did to check it.
Looking at the logs, they didn't actually start heating but they did stop cooling which caused the ruckus.
