It’s older. Between 2000-2003 maybe
HVAC Technician: HVAC Guru, HVAC TECH replied 8 months ago

Make sure the terminals for the batteries are tight and clean if they are and you still see BAT LO the thermostat will need to be changed out that is an old thermostat. I would recommend a new Vision Pro unit. You can also try to insert the batteries in backwards for 3 secs then the right way to completely reset the thermostat. Other than that it may be time for a new one.
