This thermostat (Allied Air Comfort Sync 103796-03 1.841197) is used but is in good condition cosmetically and functions as intended. It may have minor scratches\imperfections. The bracket has screw marks from the previous install. (See pictures for detail)

I have tested the thermostat and reset it back to factory default when I was done. (See last picture for more about "factory default"). I ran it for 24 hours through multiple heat or air cycles on my system. I have included pictures of the Thermostat during the test.
