Insteon 2241TH Thermostats stuck in C??

[CoolToys]

After a recent series of power outages (yes I ordered a Tesla power wall 3), both of my insteon 2441TH  thermostats transitioned to centigrade.  I still have the owners manuals but pushing the reset button doesn't do anything.  In fact now none of the buttons work. I can no longer manually over ride the temperature.   Does anyone know of a way to change it back via the eisy admin panel?  Any one ever seen this?  I don't see it as an option.  I tried unplugging the PLM and still no luck.  Too cheap to buy two more thermostats....
