HVAC coding

Can someone explain what the active option in photo actually does? It says 'cold (countries with hot weather) with recirculation status'. How exactly does it differ from the standard 'cold (countries with hot weather)' option right above it? Thanks!
Regarding the HVAC coding in photo, I have a quick update. I’ve actually tested both settings, and when I set the temperature to 'LO', I notice absolutely no difference in blower or flap behavior between the two.
Does the 'with recirculation status' option only make a difference when the AC is running in Auto mode, or is there something else I'm missing? Would love to hear your experiences!
