Abstract:
Methods and devices for controlling a heating, ventilation, and air conditioning (HVAC) system by a thermostat are provided. Input can be received from a user via a thermostat, the input being indicative of an adjustment of an HVAC-related setting. On a real-time basis, the HVAC-related setting that is being adjusted can be compared against a feedback criterion designed to indicate a circumstance under which feedback is to be presented to the user. The circumstance can be indicative of an achievement of a HVAC-related setting of a predetermined responsibility level with respect to an energy usage of the HVAC system. Upon a real-time determination that the feedback criterion is satisfied, visual feedback can be caused to be presented to the user in real-time. The real-time feedback can include a visual icon having a visual appeal corresponding to a desirability of the satisfaction of the feedback criterion.
Abstract:
A thermostat user interface for a network-connected thermostat is described. The thermostat includes a frustum-shaped shell body having a circular cross-section and a sidewall extending between first and second ends, the second end being user-facing when the thermostat is wall-mounted; a circular rotatable ring being user rotatable for adjusting a setting of the thermostat; and a circular cover including a clear circular center portion surrounded by a painted outer portion. The clear circular center portion permits a corresponding circular portion of a non-circular dot-matrix color display element to be visible through the circular cover and the painted outer portion masks a remaining portion of the non-circular dot-matrix color display element so as to create a circular graphical user interface.
Abstract:
An occupancy sensing electronic thermostat is described that includes a thermostat body, an electronic display that is viewable by a user in front of the thermostat, a passive infrared sensor for measuring infrared energy and an infrared energy directing element formed integrally with a front surface of the thermostat body. The passive infrared sensor may be positioned behind the infrared energy directing element such that infrared energy is directed thereonto by the infrared energy directing element. The thermostat may also include a temperature sensor and a microprocessor programmed to detect occupancy based on measurements from the passive infrared sensor.
Abstract:
A user-friendly, network-connected learning thermostat is described. The thermostat is made up of (1) a wall-mountable backplate that includes a low-power consuming microcontroller used for activities such as polling sensors and switching on and off the HVAC functions, and (2) separable head unit that includes a higher-power consuming microprocessor, color LCD backlit display, user input devices, and wireless communications modules. The thermostat also includes a rechargeable battery and power-stealing circuitry adapted to harvest power from HVAC triggering circuits. By maintaining the microprocessor in a “sleep” state often compared to the lower-power microcontroller, high-power consuming activities, such as learning computations, wireless network communications and interfacing with a user, can be temporarily performed by the microprocessor even though the activities use energy at a greater rate than is available from the power stealing circuitry.
Abstract:
A system including a thermostat user interface for a network-connected thermostat is described. The system includes a thermostat including a frustum-shaped shell body having a circular cross-section and a circular rotatable ring, which is user rotatable for adjusting a setting of the thermostat. The system further includes a client application that is operable on a touch-screen device separate from the thermostat, that displays a graphical representation of a circular dial, that detects a user-input motion proximate the graphical representation, that determines a user-selected setpoint temperature value based on the user-input motion, that displays a numerical representation of the user-selected setpoint temperature value, and that wirelessly transmits to the thermostat data representative of the user-selected setpoint temperature.

Abstract:
An electronic thermostat is described that includes a head unit, a rotatable ring, a backplate, an electronic display that is viewable by a user in front of the thermostat, a printed circuit board, and a daughter circuit. The daughter circuit is coupled to the printed circuit board, and senses motion of the rotatable ring and includes a first temperature sensor. A second temperature sensor separated from the first temperature sensor, are both used to calculate ambient temperature. The first temperature sensor is positioned at least partially within a cavity formed between a front surface of the head unit and the printed circuit board.
