Rather than setpoints I am talking about the amount of energy in the air outside and locked into the thermal mass of the building.

If the AC got turned off last night the building is sort of like the burning embers of a fire that will reheat the room, then at 8 or 9am you are at 30C and your building is getting that energy too.

To win that race your AC may need to come in early and start bailing out BTUs before the race begins. Even earlier than a yogi rises from bed to their practice!

The 25c setting is usually a basic thermometer and then on/off or maybe power adjustment to the unit.
