Abstract
An integrated device in an HVAC system is configured to modify an environmental condition of a building. The device includes a valve configured to regulate the flow of fluid through a conduit, an actuator comprising a motor and a drive device, and a communications mechanism. The communications mechanism is configured to receive a flow rate setpoint from an external control device of an outer control loop. The device further includes a processing circuit. The processing circuit is configured to determine an actuator position setpoint using a cascaded feedback control mechanism based on the flow rate setpoint and a flow rate measurement from a flow rate sensor of an inner control loop. The valve, the actuator, the communications mechanism, and the processing circuit are located within a common integrated device chassis.
