Zusammenfassung:A building temperature may be allowed to deviate from a comfort temperature set point to an energy saving temperature when a user is outside the geo-fence. Crossing information indicating when a user crosses into the geo-fence may be received. The crossing information may be stored over time to develop a history of when the user crosses into the geo-fence. A probability function that operates on at least part of the stored crossing information may be used to predict a time range of when the user is expected to next arrive at the building, the time range having a starting time and an ending time. The HVAC system may be instructed to drive the building temperature to an intermediate temperature at the starting time of the time range, wherein the intermediate temperature is between the energy saving temperature and the comfort temperature set point.
