A method of determining a lifetime parameter of a capacitor in a failsafe device includes measuring an amount of energy required to return the failsafe device to a failsafe position, measuring an effective capacitance of the capacitor, and comparing the amount of energy to the effective capacitance to determine the lifetime parameter of the capacitor.

A flow control device for controlling flow in a heating, ventilation, or air conditioning (HVAC) system is shown. The flow control device includes a valve body including an inlet path, an outlet path, a valve member, and a valve stem coupled to the valve member. The flow control device includes a first sensor configured to obtain pressure measurements within the valve body, a second sensor configured to obtain displacement measurements of the valve stem, and a controller including a processing circuit configured to determine a flowrate based at least on the pressure measurements from the first sensor and the displacement measurements from the second sensor.

A sensor in a building HVAC system includes a transducer configured to measure a variable in the building HVAC system and to generate a sensor reading indicating a value of the measured variable. The sensor includes a communications interface configured to provide the sensor reading to a control device in the building HVAC system and a near field communication (NFC) circuit separate from the communications interface. The NFC circuit is configured to facilitate bidirectional NFC data communications between the sensor and a mobile device. The sensor includes a processing circuit having a processor and memory. The processing circuit is configured to wirelessly transmit data stored in the memory of the sensor to the mobile device via the NFC circuit, wirelessly receive data from the mobile device via the NFC circuit, and store the data received from the mobile device in the memory of the sensor.

An actuator in a HVAC system includes a mechanical transducer, a processing circuit, a wireless transceiver, and a power circuit. The processing circuit includes a processor and memory and is configured to operate the mechanical transducer according to a control program stored in the memory. The wireless transceiver is configured to facilitate bidirectional wireless data communications between the processing circuit and an external device. The power circuit is configured to draw power from a wireless signal received via the wireless transceiver and power the processing circuit and the wireless transceiver using the drawn power. The processing circuit is configured to use the power drawn from the wireless signal to wirelessly transmit data stored in the memory of the actuator to the external device via the wireless transceiver, wirelessly receive data from the external device via the wireless transceiver, and store the data received from the external device in the memory.

An integrated device in an HVAC system is configured to modify an environmental condition of a building. The integrated device includes a valve configured to regulate a flow of a fluid through a conduit and an actuator. The actuator includes a motor and a drive device. The drive device is driven by the motor and coupled to the valve for driving the valve between multiple positions. The integrated device further includes a processing circuit coupled to the motor. The processing circuit is configured to detect device identifying information for the valve or the actuator and to detect the integrated device location within the building.

Integrated smart actuator and valve device applications

An actuator includes a drive device, and energy storage element and an actuator controller. The energy storage element is charged during operation of the actuator using power from an external power source. The drive device drives a valve member to a failsafe setpoint using energy from the energy storage element in the event of a power loss during operation of the actuator. The actuator controller provides a drive signal to the drive device indicating the valve member orientation (i.e. the failsafe setpoint) to which the drive device is to drive the valve member. The failsafe setpoint is determined based on the last fluid source that was controlled by the actuator of the fluid system prior to the power outage.

A building management system is configured to modify an environmental condition of a building. The building management system includes a valve assembly, an actuator device, and a network sensor device. The actuator device includes a motor, a drive device driven by the motor and coupled to the valve assembly, and a controller coupled to the motor. The controller includes a microprocessor and a control application configured to enable closed loop control of the valve assembly. The network sensor device is communicably coupled to the actuator device and configured to measure an environmental property. The control application is configured to perform the closed loop control of the valve assembly based on an input control signal from a mobile device and the measured environmental property from the network sensor device.
