SYSTEMS AND METHODS FOR DETERMINING OR MODIFYING A TEMPERATURE PROGRAM BASED ON OCCUPANT ACTIVITY
First Claim
1. A method, comprising:
- thermostatically controlling a heating, ventilation, and cooling (HVAC) system of a structure over a plurality of days according to a temperature setpoint schedule, wherein the temperature setpoint schedule comprises a plurality of temperature setpoints that each have an associated temperature and an associated time;
collecting occupant activity data indicative of types or degrees of occupant activity in the structure over the plurality of days;
processing the occupant activity data in conjunction with the plurality of temperature setpoints to identify a temperature setpoint of the plurality of temperature setpoints, wherein the identified temperature setpoint is associated with a statistically detectable change between a first type or degree of occupant activity occurring in the occupant activity data prior to the associated time of the identified temperature setpoint and a second type or degree of occupant activity occurring in the occupant activity data subsequent to the associated time of the identified temperature setpoint; and
during a time window that includes the associated time of the identified temperature setpoint;
detecting the change between the first type or degree of occupant activity and the second type or degree of occupant activity in the occupant activity data occurring at a particular time; and
implementing the associated temperature of the identified temperature setpoint in response to the detected change regardless of whether the particular time is prior to, the same as, or subsequent to the associated time of the identified temperature setpoint.

Abstract
The present disclosure relates to thermostatically controlling a HVAC system according to a temperature program that is at least partially responsive to observed or predicted changes in the type or degree of occupant activity. For example, a thermostat may process collected occupant activity data in conjunction a temperature program to identify a particular temperature setpoint that is associated with a statistically detectable change between a first and a second type or degree of occupant activity. During a time window that includes the identified temperature setpoint, if the thermostat detects the change between the first and the second type or degree of occupant activity in the occupant activity data, the thermostat may responsively implement the temperature associated with the identified temperature setpoint, regardless of whether the current time is prior to, the same as, or subsequent to the time associated with the identified temperature setpoint.

19. A method, comprising:
-
thermostatically controlling a heating, ventilation, and cooling (HVAC) system of a structure over a period of time according to a temperature program comprising a plurality of temperature setpoints; collecting occupant activity data describing occupant activity types or degrees over the period of time, wherein the period of time is divided into a plurality of time windows that each begin at an occurrence of a statistically different occupant activity type or degree in the occupant activity data; processing the occupant activity data in conjunction with the plurality of temperature setpoints to identify a temperature setpoint of the plurality of temperature setpoints, wherein the identified temperature setpoint has an associated temperature, an associated time, and an associated time window of the plurality of time windows that includes the associated time; during the associated time window of the identified temperature setpoint; detecting a change from a first type or degree of occupant activity to a statistically different second type or degree of occupant activity in the occupant activity data occurring at a particular time; and implementing the associated temperature of the identified temperature setpoint in response to the detected change regardless of whether the particular time is prior to, the same as, or subsequent to the associated time of the identified temperature setpoint. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27, 28)

29. A method, comprising:
-
thermostatically controlling a heating, ventilation, and cooling (HVAC) system of a structure according to a temperature program comprising a plurality of occupant activity-based temperature setpoints, wherein each occupant activity-based temperature setpoint is associated with a temperature and with a change between a first type or degree of occupant activity and a statistically different second type or degree of occupant activity; collecting occupant activity data describing occupant activity types or degrees; detecting, in the occupant activity data, the change from the first type or degree of occupant activity to the second type or degree of occupant activity; and implementing the temperature associated with the occupant activity-based temperature setpoint responsive to the detected change regardless of a current time. - View Dependent Claims (30, 31, 32, 33, 34)
