Trane tcont802as32da thermostat when programmed the wake, leave, & return temps all change correctly, but the sleep temp dose not change , but when you check the setting the sleep setting is blinking and the correct temp is there?
Since the thermostat has worked properly and assuming you have made no changes to the system, then I would try replacing the batteries as a last attempt. Unless there's an obvious change in your system, it seems the problems you face could be due to the thermostat especially since you're replaced it 3 times. You might review all the installer settings in case one has become changed by an act of a poltergeist.
