Not sure if this will help, but I have a TX1500uc / TX1500 Thermostat and the

took the batteries out, pressed and held the front buttons, pressed the RESET
button inside the unit, even swapped the Elec/Gas jumper temporarily. Put
everything back the way it was and popped the unit back on the wall and it was
good.
