    Abstract: A method of operating a heating ventilation and air conditioning (HVAC) system by a thermostat to control an environmental parameter of a plurality of conditioned spaces is described. The method includes detecting a first value of the environmental parameter of the first conditioned space, the first value being detected by the thermostat, controlling the HVAC system based on the first value of the environmental parameter and a first setpoint for the environmental parameter, receiving, from a first occupancy indicator, a first indication of occupancy of a second conditioned space of the plurality of conditioned spaces, the first occupancy indicator being a human actuated occupancy indicator, and controlling the HVAC system based at least in part on the received first indication of occupancy of the second conditioned space.

    Abstract: A gas valve assembly includes a gas valve and a control circuit. The gas valve is configured for variably controlling a flow of gas through the gas valve assembly. The control circuit includes a controller programmed to determine a first setting for the gas valve in response to a received commanded flow, adjust the first setting to a second setting based on a measured temperature when the measured temperature is one that may induce changes to the flow of gas through the gas valve assembly, and control the gas valve based on the second setting.

    Abstract: In an exemplary embodiment, a hot surface ignition module is configured to receive user input settings for one or more HVAC system configuration parameters wirelessly transmitted by a mobile device to the hot surface ignition module. The hot surface ignition module is configured to store the received user input settings for the one or more HVAC system configuration parameters to control the at least one HVAC component according to the received user input settings for the one or more HVAC system configuration parameters. The hot surface ignition module may be configured such that the NFC short-range wireless communication with the mobile device enables the hot surface ignition module to receive and store the user input settings for the one or more HVAC system configuration parameters without requiring the hot surface ignition module to be connected with an electrical power source, Wi-Fi, and/or cellular service

    Abstract: FIG. 1 is a front perspective view of a low profile electronic device such as a thermostat showing the new design;
    FIG. 2 is a front view thereof.
    FIG. 3 is a rear view thereof.
    FIG. 4 is a right side view thereof.
    FIG. 5 is a left side view thereof.
    FIG. 6 is a top view thereof.
    FIG. 7 is a bottom view thereof.
    FIG. 8 is a top view of a second embodiment of a low profile electronic device showing the new design. All other views of the second embodiment are identical; and,
    FIG. 9 is a top view of a third embodiment of a low profile electronic device showing the new design. All other views of the third embodiment are identical.
    The ornamental design claimed is shown in solid lines in the drawings. Broken lines, if present in the drawings, are for illustrative purposes only and form no part of the claimed design. The stippling in FIGS. 6, 8, and 9 is used to indicate a contrast in appearance between the transparent lens and the front surface of the electronic device, with no specific color, material, texture, or other feature being claimed. The stippling does not indicate a contrast in appearance between the front surface of the electronic device and portions of the electronic device other than the transparent lens.

    Abstract: Disclosed are exemplary embodiments of systems and methods for controlling inducer motor speed. In an exemplary embodiment, a method includes changing stator voltage of an inducer motor (e.g., by changing a firing angle of a triac, using a transistor, a silicon controlled rectifier or semiconductor controlled rectifier (SCR), other switching device, etc.); determining actual inducer motor speed (e.g., by using a hall effect sensor or other speed sensor, etc.); and after determining the actual inducer motor speed, changing the motor stator voltage (e.g., by changing the firing angle of the triac, etc.) to a value at which the actual inducer motor speed is controllably regulated and/or maintained substantially at a set speed.
