Bright idea: reusing a thermostat

    When the repairmen put in the new furnace, they also replaced the thermostat, leaving us the old one. 

    This particular thermostat, which we'd put in a couple of years ago, had a few bells and whistles ...  including a battery-operated thermometer.  

     So rather than throw it in the garage sale pile, I moved it upstairs.  (Where it it currently 71 degrees).  I may move it around, just to see how well the furnace is doing.
