Patent number: 10895883Abstract: 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.
