    Abstract: A system for detection of equipment connections to a thermostat. The thermostat may have one or more terminals with a one-to-one connection to one or more loads respectively of heating, ventilation and/or air conditioning equipment, and one or more terminals with a one-to-one connection to electrical power. One or more detectors may be connected one-to-one to each of the one or more terminals, respectively, for connection to the one or more loads, and the one or more connections to the electrical power. Each detector may be connected to a processor. Each detector may be configured to provide a signal to the processor relative to a corresponding terminal indicating a status of a connection of the terminal to a load or to the electrical power.

    Abstract: A thermostat device may use one or two temperature sensors inside the housing of the thermostat device to perform temperature compensation to determine the ambient temperature outside the housing of the thermostat device. Processing circuitry of the thermostat device may determine a current operating mode of the thermostat device out of a plurality of operating modes. The processing circuitry may also use machine learning to estimate the current and voltage of the thermostat device based on temperature differences between the two temperature sensors. The processing circuitry may determine, based at least in part on the estimated current and voltage of the thermostat device and the current operating mode of the thermostat device, an ambient temperature outside the housing of the thermostat device.

    Abstract: A Heating, Ventilation, and Air Conditioning (HVAC) controller may include a housing, a display, a printed wiring board, a flextail, and a temperature sensor. The housing may be configured to house the display, the printed wiring board, the flextail, and the temperature sensor. The flextail may extend from, for example, the display or other component of the HVAC controller, along the interior surface of the housing, and connect to a connector on the printed wiring board. The temperature sensor may be mounted on the flextail, and connected to the printed circuit board via the flex tail or other connection. In some cases, the temperature sensor may be positioned on the flextail such that when the flextail is connected to the printed wiring board, the temperature sensor is positioned adjacent a lower part of the housing, where less internal heat generated by the internal electrical components of the HVAC controller will reside.
