I had a low battery message on my maple/chase 0960t-1 thermostat. Batteries were replaced but getting no reading on the thermostat. What could be the problem?

Make sure you didn't install one backwards. Its easy to do.

Thanks a lot. Boy am I an idiot. Just saw it on the user manual. Thanks again.

You aren't the first person to do it, and won't be the last... I've even done it myself.
