GEO-FENCING WITH ADVANCED INTELLIGENT RECOVERY
First Claim
1. A method of implementing advanced intelligent recovery in an HVAC system for a building, the HVAC system implementing geo-fencing using a geo-fence that is defined for the building or a user of the building, the method comprising:
- allowing a building temperature to deviate from a comfort temperature set point to an energy saving temperature when a user is outside the geo-fence;
receiving crossing information indicating when a user crosses into the geo-fence;
storing the crossing information over time to develop a history of when the user crosses into the geo-fence;
processing at least some of the stored crossing information to determine a comfort time that is related to when the user is expected to next arrive at the building; and
instructing the HVAC system to drive the building temperature towards the comfort temperature set point based on the comfort time.

Abstract
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.

13. An HVAC control system for controlling operation of HVAC equipment within a building, the HVAC control system configured to be in operative communication with a user'"'"'s mobile device running an executable program providing geo-fence functionality, the HVAC control system comprising:
-
an input for receiving crossing information indicating when the user'"'"'s mobile device crosses into a geo-fence that is defined for the building; a memory for storing the crossing information over time to develop a history of when the user'"'"'s mobile device crosses into the geo-fence; a controller operatively coupled to the input and the memory, the controller configured to control the HVAC equipment and allow a building temperature in the building to deviate from a comfort temperature set point to an energy saving temperature when the user'"'"'s mobile device is outside the geo-fence; the controller is further configured to use a probability function that operates on at least part of the stored crossing information to predict a time range of when the user'"'"'s mobile device is expected to next arrive at the building, the time range having a starting time and an ending time; and the controller is further configured to control the HVAC equipment 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. - View Dependent Claims (14, 15, 16, 17)

18. An HVAC controller configured to operate HVAC equipment within a building, a user of the building having a mobile device with location services, the HVAC controller comprising:
-
a memory for storing at least two targets, one of the at least two targets including a starting time point and an intermediate temperature set point, and another of the at least two targets including an ending time point and a comfort temperature set point; a communications module for receiving the at least two targets from a remote server; an equipment interface for providing control signals to the HVAC equipment; a controller operably coupled to the memory, the communications module and the equipment interface; the controller configured to operate the HVAC equipment, via the equipment interface, in accordance with at least two targets received via the communications module and stored in the memory; and the controller further configured to calculate one or more heating or cooling ramps based upon the at least two targets such that the building will attain the intermediate temperature set point at a time corresponding to the starting time point and the building will attain the comfort temperature set point at or before the ending time point. - View Dependent Claims (19, 20)
