First Claim
1. A sensing and control unit comprising:
- a passive infrared sensor;
an active infrared sensor, wherein the passive infrared sensor and the active infrared sensor are positioned behind a darkened front cover of the sensing and control unit such that the darkened front cover of the sensing and control unit conceals the passive infrared sensor and the active infrared sensor from the view of a user;
an electronic display having a first mode and a second mode, wherein;
the first mode of the electronic display causes the sensing and control unit to use a first amount of power;
the second mode of the electronic display causes the sensing and control unit to use a second amount of power; and
the first amount of power is less than the second amount of power; 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 control setting of the sensing and control unit to an energy-saving setting 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 sensing and control unit, wherein the one or more processors detect a person approaching the sensing and control unit 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.
