    Honeywell Rth2300?
    New thermostat, brand new batteries. It's all connected but no display! I can turn it on and it runs but I have no idea of the temperature. Any help?

    If the new thermostat is connected correctly and you have no display I would suspect a defective thermostat. Time to go back to where you got it and get a replacement.

    Thanks for the quick reply. That would be my first thought except the one I just replaced wouldn't display either. Now I'm thinking maybe it wasn't broken. I've checked and rechecked the wiring. I'm at a loss.
