Abstract: A Heating, Ventilation, and/or Air Conditioning (HVAC) controller configured to control at least part of an HVAC system of a building. The HVAC controller may include a user interface and a controller. In response to a selection by a user at the user interface, the controller may assemble and present via the user interface an output that encodes settings in a machine readable form. The controller may display the encoded settings on the display with fixed segments of a fixed segment display. An application program code on a remote device may be utilized to capture the displayed fixed segments that encode the settings in an image. The captured image of fixed segments may be decoded at the remote device or may be sent to a remote computing device for processing and/or decoding.

Abstract: In some examples, a method for controlling the heating, ventilation, and air conditioning (HVAC) system in a building includes receiving user input indicating a fallback temperature sensor from a plurality of temperature sensors in the building, the plurality of temperature sensors in the building being associated with a plurality of spaces within the building. The method also includes determining, by the controller, that the plurality of spaces within the building are unoccupied. The method further includes determining, by the controller, a temperature sensed by the fallback temperature sensor based on communication between the controller and the fallback temperature sensor. The method includes causing, by the controller, the HVAC system to turn on or off based on the temperature at the fallback temperature sensor in response to determining that the plurality of spaces within the building are unoccupied.

Abstract: The occupancy status of a building space may be determined by sensing an indication of motion in the building space, in response to sensing the indication of motion in the building space, starting an occupied time period having a length during which the building space is indicated as being occupied, determining a measure related to a number of subsequent sensed indications of motion in the building space during the occupied time period, and selectively adjusting the length of the occupied time period based on the measure related to the number of subsequent sensed indications of motion in the building space during the occupied time period.

Abstract: An HVAC controller includes a first input terminal configured to be electrically coupled with a first field wire and a second input terminal configured to be electrically coupled with a second field wire, and a double pole relay including two input terminals and two output terminals. Control circuitry is operably coupled to the temperature sensor and the double pole relay and is configured to determine whether the first field wire is electrically coupled with the first input terminal and whether the second field wire is electrically coupled with the second input terminal.

Abstract: A controller for operating HVAC equipment of a building having one or more windows. The HVAC equipment includes a heater and a humidifier. The controller receives an indoor temperature and an outdoor temperature, determines a thermal efficiency of the building based on the indoor temperature, the outdoor temperature and control signals provided to the heater indicative of a thermal demand on the heater, determines a window efficiency setting based on the thermal efficiency, determines a humidity threshold based on the window efficiency setting and the outdoor temperature, and controls the humidifier of the building to not raise the humidity in the building above the humidity threshold.

Abstract: An HVAC controller may be programmed to execute a guided set up routine that may guide a user through configuring the thermostat to control a particular HVAC system configuration based, at least in part, on which wires from the HVAC system are connected to terminals of the HVAC controller. The guided set-up routine may be accessible through a user interface provided at a remote device that a user may utilize to interact with the HVAC controller from a remote location.

Abstract: A remote control unit for interacting with one or more thermostats controlling an HVAC system may be mounted on wall near a point of entry to a building. The remote control unit may include a first selectable mode option corresponding to a first operating mode of the thermostat and a second selectable mode option corresponding to a second operating mode of the thermostat. The remote control unit may wirelessly send one or more commands to a thermostat to operate in one or more modes at a predetermined temperature associated with that mode.

Abstract: A building control network may have a first central device, a second central device and one or more peripheral devices. An illustrative method may include placing the second central device into an associate mode, and sending an associate command from a perimeter device to associate the perimeter device with the second central device. The associate command may be received by the first central device. The first central device may send one or more commands to the second central device, where the one or more commands may cause the second central device to be taken out of its associate mode and to reconfigure the second central device to a perimeter device. The first central device may then be put in an associate mode, and both the second central device and the perimeter device may be associated as perimeter devices with the first central device.
