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.
