Thermostat

One day, Barb noticed that there was a strange message on the screen of the thermostat.  We couldn’t figure out what it said.  So Barb found the manual that the lady before us had left behind.  She read it and found out the message said Lo Batt meaning low battery. Barb went out and got a new battery and fixed the thermostat.  We were lucky that it happened while we were still here and not when we were in Florida.
