USER-FRIENDLY, NETWORK CONNECTED LEARNING THERMOSTAT AND RELATED SYSTEMS AND METHODS
First Claim
1. A thermostat for controlling an HVAC system in an enclosure, the thermostat comprising:
- a passive infrared sensor;
an active infrared sensor;
an electronic display having a first mode and a second mode; and
one or more processors coupled to the passive infrared sensor, the active infrared sensor, and the electronic display, the one or more processors being programmed to;
change a setpoint temperature of the thermostat to an energy-saving temperature upon detection of a non-occupancy condition for the enclosure, wherein the one or more processors detect the non-occupancy condition based at least in part on readings received from the passive infrared sensor; and
change the electronic display from the first mode to the second mode upon detection of a person approaching the thermostat, wherein the one or more processors detect a person approaching the thermostat based at least in part on readings received from the active infrared sensor.

Abstract
A thermostat for controlling an HVAC system in an enclosure may include a passive infrared sensor, an active infrared sensor, and an electronic display having a first mode and a second mode. The thermostat may also include one or more processors programmed to change a setpoint temperature of the thermostat to an energy-saving temperature upon detection of a non-occupancy condition for the enclosure. The processor(s) may detect the non-occupancy condition based at least in part on readings received from the passive infrared sensor. The processor(s) may also be programmed to change the electronic display from the first mode to the second mode upon detection of a person approaching the thermostat. The processor(s) may detect a person approaching the thermostat based at least in part on readings received from the active infrared sensor.

9. A method for controlling an HVAC system in an enclosure using a thermostat, the method comprising:
-
operating a passive infrared sensor of the thermostat; operating an active infrared sensor of the thermostat; operating an electronic display of the thermostat in a first mode; receiving, by one or more processors of the thermostat, readings from the passive infrared sensor and readings from the active infrared sensor; detecting, by the one or more processors, a non-occupancy condition for the enclosure based at least in part on readings received from the passive infrared sensor; changing, by the one or more processors, a setpoint temperature of the thermostat to an energy-saving temperature upon detection of the non-occupancy condition for the enclosure; detecting, by the one or more processors, a person approaching the thermostat based at least in part on readings received from the active infrared sensor; and changing, by the one or more processors, the electronic display from the first mode to a second mode upon detection of the person approaching the thermostat. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A non-transitory storage medium, comprising instructions that, when executed by one or more processors, cause the one or more processors to perform operations comprising:
-
receiving readings from a passive infrared sensor; detecting a non-occupancy condition for an enclosure based at least in part on the readings received from the passive infrared sensor; changing a setpoint temperature of a thermostat to an energy-saving temperature upon detection of the non-occupancy condition for the enclosure; receiving readings from an active infrared sensor; detecting, by the one or more processors, a person approaching the thermostat based at least in part on readings received from the active infrared sensor; and changing, by the one or more processors, an electronic display of the thermostat from a first mode to a second mode upon detection of the person approaching the thermostat. - View Dependent Claims (18, 19, 20)
