    Abstract: An actuator in a HVAC system includes an inductive sensor, a conductive target, and a controller. The conductive target has multiple different portions that become aligned with the inductive sensor as a position of the actuator changes. Each of the multiple different portions have a different inductance. The controller receives a signal from the inductive sensor indicating an observed inductance of the portion of the conductive target aligned with the inductive sensor. The controller uses a stored relationship between the observed inductance and the position of the actuator to determine the position of the actuator based on the observed inductance. The controller operates the actuator to change the position of the actuator based on the determined position.

    Abstract: A system including a valve positioned in a conduit, wherein the valve is configured to change fluid flow through the conduit. The system includes an actuator having a motor that is configured to selectively rotate the valve toward a desired valve orientation. The system is configured to receive a request for a desired valve orientation, control the motor to move the valve into the desired valve orientation, and sense a condition corresponding to a current valve orientation following movement by the motor. The system is configured to determine if the sensed condition indicates that the current valve orientation matches the desired valve orientation from the request, and, responsive to determining that the current valve orientation does not match the desired valve orientation from the request, control the motor to selectively rotate the valve in a direction to move the valve towards the desired valve orientation.

    Abstract: During installation, an engagement structure of an actuator assembly positioning device restricts movement of a securement element of an anti-rotation bracket past a target location (e.g. midpoint) relative to a securement slot of an thereby, thereby guiding a user in positioning the anti-rotation bracket and actuator in a desired mounting arrangement. An optional constricting structure of the positioning device provides tactile feedback that the desired arrangement of the anti-rotation bracket and actuator has been reached. Upon being subject to a force in excess of a threshold force (e.g., as a result of eccentric loading on the actuator arising from an off-centered mounting of the actuator relative to a rotatable shaft), the engagement structure transitions to a second configuration in which the securement element is allowed to move past the target location, thereby accommodating eccentric movement of the actuator during operation.

    Abstract: An actuator in a HVAC system includes a housing having an interior-facing surface and an exterior-facing surface. The actuator includes magnetic field sensor(s) located within the housing and arranged adjacent to the interior-facing surface. The actuator includes a user input device retaining magnet(s) that are movable into multiple different positions along the exterior-facing surface of the housing. An actuator controller includes a magnet locator that determines a location of the magnet(s) with respect to the magnetic field sensor(s) based on data generated by the magnetic field sensor(s). The actuator controller also includes a settings generator that generates settings for the actuator based on the location of the magnet(s) determined via the magnet locator.

    Abstract: A remote mount kit for a damper in an HVAC system is provided. The remote mount kit includes a mounting bracket. The mounting bracket includes a first mounting flange having a first mounting hole pattern and a second mounting flange having a second mounting hole pattern. The remote kit also includes a drive shaft having a first drive end and a second drive end. The first drive end and the second drive end are configured to couple to an actuator. The remote kit further includes a crank shaft and a connector configured to couple the crank shaft to the damper. A dimension between the holes of the first mounting hole pattern is smaller than a dimension between the holes of the second mounting hole pattern.

    Abstract: A fire damper actuation system in an HVAC system includes a damper system and an actuator system. The damper system includes damper blades rotatable between an open configuration and a closed configuration, a crank arm assembly configured to drive the damper blades, a spring assembly configured to be held in a loaded condition when the damper blades are in the open configuration, a temperature-activated fusible link, and a fusible link arm coupling the temperature-activated fusible link to the crank arm assembly. The actuator system includes a motor and a drive device. The drive device is coupled to the crank arm assembly and the temperature-activated fusible link. Operation of the drive device by the motor between a first end stop location and a second end stop location simultaneously rotates the crank arm assembly and the temperature-activated fusible link to complete a test inspection procedure.

    Abstract: Systems and methods for controlling flow with a 270 degree rotatable valve are provided. A described system includes a valve body having a valve chamber and a plurality of ports into the valve chamber. The plurality of ports include a first port, a second port, and a third port. The first port and the second port are aligned with a common axis and located on opposite sides of the valve chamber. The system further includes a valve member located within the valve chamber. The valve member is controllably rotatable by approximately 270 degrees to modulate fluid flow between the first port and the third port while maintaining the second port completely closed and to modulate fluid flow between the second port and the third port while maintaining the first port completely closed.
