Abstract: A control system for a heating, ventilation, and/or air conditioning (HVAC) system includes a controller. The controller is configured to control the HVAC system to condition an air flow based on first feedback from a first sensor of the HVAC system, receive second feedback from a second sensor of the HVAC system, and control the HVAC system to condition the air flow based on the second feedback instead of the first feedback when the first feedback from the first sensor being no longer available. The first feedback is indicative of a first operating parameter of the HVAC system, and the second feedback is indicative of a second operating parameter of a refrigerant flowing through the HVAC system.

Abstract: A heating, ventilating, and air conditioning (HVAC) includes a processor and a plurality of sensors. The plurality of sensors can collect a first set of data indicative of environmental conditions of a structure in which the HVAC control device is located. The HVAC control device can control operational settings of an HVAC system that can supply conditioned air to the structure and operate the HVAC system in a default mode. The HVAC control device can also receive a second set of data collected by one or more sensors of a secondary input device and receive a signal from the secondary input device. Additionally, the HVAC control device can implement an override mode of the control device based on the signal. Implementation of the override mode effectuates a change in the operational settings of the HVAC system.

Abstract: A terminal unit for a heating, ventilation, and air conditioning (HVAC) system includes a housing defining a plenum and having a first panel and a second panel disposed opposite each other. The first panel has a first outlet opening and a second outlet opening, and the second panel has a first inlet opening configured to receive a first air flow and a second inlet opening configured to receive a second air flow. The terminal unit includes a sound attenuator including an inlet configured to receive the first air flow and an outlet configured to discharge the first air flow into the housing via the first inlet opening. The terminal unit further includes first and second blowers. The first blower is configured to discharge air from the plenum via the first outlet opening, and the second blower is configured to discharge air from the plenum via the second outlet opening.

Abstract: A controller for HVAC equipment of a plant includes a processing circuit configured to predict an impact of a time delay of the plant on a performance variable received as feedback from the plant. The processing circuit is configured to artificially increase or decrease a value of the performance variable using an adjustable time delay parameter to at least partially negate the impact of the time delay on the performance variable. The processing circuit is configured to use the artificially increased or decreased value of the performance variable in on-off feedback control to operate the HVAC equipment.
