Put brand new batteries in the unit and it still flashes "Repl Bat".
Cleaned the contacts and checked the batteries. What to look for?

Check the nominal required voltage of the old and the new batteries.
If the new battery has a different chemical construcyion,
the voltage will be different.

If they are the correct batteries, I'd be looking for a new
thermostat. I'd let it sit without the batteries for an hour or
so just to make sure it's fully reset.

Had the same problem. Replaced the batteries and the display still showed
'Repl Bat'.
Fixed it by pulling the batteries, putting the unit back on the wall, then
turning the power to the furnace off and back on.
That cleared the display. Put the batteries back in the unit and all was well.

Wow, can't believe that worked. I have thrown away a couple because of this. Thanks

Exactly the same.. Other than it took a few minutes after power off for screen to reset, it all went perfectly. Thanks for the exactly right answer
