Taco RMBs booting to different screens?

JeffM

I monitor a family vacation house in Maine which has three Taco RMBs running radiant zones. The RMBs don't have remote (internet) access, so I monitor their mix supply water temps with a webcam that sees the LCD displays. I noticed recently after a power failure that one of the three had rebooted to a different display than the others (it shows Outdoor temp now instead of Mix Supply). Nothing else seems to have changed, they run fine I just cant see the mix temp from one after a power outage (which happen regularly in coastal Maine). Has anyone else seen this before, or have any ideas of why it might be happening or what I could do to get this RMB to reboot the same as the others? It has happened twice now so isn't just a fluke. A simple press of the Item button resolves this of course, but that's hard to do from 2000 miles away...
