    Abstract: A heat exchanger system that includes a heat exchanger that includes a plurality of circuits wherein the heat exchanger is configured to exchange heat between a refrigerant and a working fluid. The heat exchanger system also includes a valve configured to fluidly couple a circuit of the plurality of circuits to a flow path of the refrigerant. Further, the heat exchanger system includes a controller that is configured to receive feedback indicative of an operating parameter of the heat exchanger system and actuate the valve based on the operating parameter.

    Abstract: The present disclosure relates to a heating, ventilation, and air conditioning (HVAC) unit having a vapor compression circuit including a compressor and a heat exchanger. The HVAC unit includes a controller configured to provide a first signal to control the compressor, and provide a second signal to control a variable speed fan associated with the heat exchanger based on a target speed. The HVAC unit further includes a pressure activated device coupled between the controller and the compressor, wherein the pressure activated device is configured to temporarily block the first signal from the controller while a refrigerant pressure within the vapor compression circuit is greater than a threshold value. In response to determining that the pressure activated device has blocked the first signal for at least a threshold time period, the controller is configured to both deactivate the first signal and provide the second signal for an equilibration time.

    Abstract: A thermostat for a building space includes an electronic display, a frame, a touch sensitive interface, and a processing circuit. The touch-sensitive interface has a first portion that overlays the electronic display and a second portion that overlays the frame. The touch-sensitive interface is configured to receive touch-based input via both the first portion and the second portion. The processing circuit is configured to define one or more locations within the second portion that correspond to touch-sensitive buttons. The locations of the touch-sensitive buttons are customizable and can be changed by a user. The thermostat further including at least one of a sticker and a skin that covers at least part of the second portion and visually marks the locations of the touch-sensitive buttons.
