  • BUILDING AUTOMATION SYSTEM WITH AUTOMATED SEQUENCING FOR MANAGERLESS TWINNING AND METHOD THEREOF
    Publication number: 20250314390
    Abstract: A method of and systems for staging units in a building management system (BMS) determines a next unit of the plurality of units to add to or remove from contributing to the environmental operation in each controller of the number of units in the BMS. The systems or methods also can determine in each controller of the units if a respective unit for the controller is the next unit, and changing an operational mode of the respective unit if the respective unit is the next unit. The systems and methods can implement managerless twinning control.

  • HVAC system with wireless waveguide system
    Patent number: 11913656
    Abstract: A wireless waveguide system for a heating, ventilation, and air conditioning (HVAC) system. The wireless waveguide system includes a sensor that detects an environmental condition and directs a signal indicative of the environmental condition along an interior of a ductwork. A signal sensor detects a strength of the signal within the interior of the ductwork. A repeater that operates based on the strength of the signal detected by the signal sensor and repeats the signal along a communication path at least partially within the interior of the ductwork to a controller of an HVAC unit.
