A controller for controlling operation of an actuator in an HVAC system is shown. The controller includes a processing circuit configured to receive, via a position sensor communicatively coupled to the actuator, a first voltage value, the first voltage value indicative of a first position of the actuator. The processing circuit is further configured to provide a control signal to the actuator to move to a second position. The processing circuit is further configured to, in response to the actuator moving to the second position, determine that the actuator is located in a different position than the second position based on a second voltage value via the position sensor. The processing circuit is further configured to automatically perform a fault correction process to calculate an updated stroke range of the actuator.

A HVAC controller includes a housing and one or more heat-generating components contained within the housing. The heat-generating components cause a temperature inside the housing to exceed a temperature outside the housing. The controller includes a temperature sensor configured to measure the temperature inside the housing and a controller event detector configured to detect, for at least one of the heat-generating components, a controller event that generates heat inside the housing. The controller further includes a temperature compensation module configured to identify a steady-state temperature gain associated with the detected controller event, to calculate a temperature offset using a summation of the steady-state temperature gain, to determine the temperature of the building zone outside the housing by subtracting the temperature offset from the temperature measured inside the housing, and to store the temperature offset.

Systems and methods for heat rise compensation

A method for updating heating, ventilation, or air conditioning (HVAC) devices is provided. The method includes receiving an update package at a first HVAC device of a plurality of HVAC devices via a network. The update package includes an identification of a plurality of device models and a plurality of software updates. The method includes determining that a device model for the first HVAC device is identified by the update package and in response to a determination that the device model for the first HVAC device is identified by the update package, extracting a first software update corresponding to the device model for the first HVAC device from the update package and installing the first software update on the first HVAC device. The method includes transmitting the first update package to a second HVAC device of the plurality of HVAC devices via the network.

Building management system with update ecosystem

A controller for a rooftop air handling unit includes control logic configured to generate a control signal for the HVAC device using values for one or more variables monitored by the controller. The controller includes an equipment model that links specific instances of data objects to the variables used by the control logic and a view definition that identifies one or more of the data objects. The controller includes a web server configured to dynamically generate a web portal that includes one or more of the data objects identified by the view definition. The controller includes a communications interface that provides the web portal to a client device.

A HVAC controller located within a building zone includes a housing, a wireless radio, a controller monitor, a temperature sensor, and a temperature compensation module. The wireless radio is contained within the housing and is configured to transmit data via a wireless HVAC network. The controller monitor is configured to detect wireless activity of the wireless radio, the wireless activity generating heat inside the housing and causing a temperature inside the housing to exceed a temperature of the building zone outside the housing. The temperature sensor is configured to measure the temperature inside the housing. The temperature compensation module is configured to determine a wireless heat rise resulting from the wireless activity, to calculate a temperature offset based on the wireless heat rise, and to determine the temperature of the building zone outside the housing by subtracting the temperature offset from the temperature measured inside the housing.

Implementations herein relate to visualization of interaction with a building management system (BMS). Such interaction may be facilitated with a smart headset that displays a three-dimensional model of an image with real-time data from the BMS to enable monitoring and control of the BMS. In one implementation, a system for locating a target in a building includes a server, a first wireless emitter, and an application on a mobile device. The first wireless emitter is associated with the target and configured to emit a first emitter identifier within a first range. The application is configured to detect the first emitter identifier when the mobile device is within the first range. The application is also configured to transmit the first emitter identifier to the server in response to detecting the first emitter identifier. The application is also configured to receive a first content from the server.

Systems and methods for enhancing building management system interaction and visualization

A method for detecting and responding to disturbances in a HVAC system using a noisy measurement signal and a signal filter is provided. The method includes detecting a deviation in the noisy measurement signal, resetting the filter in response to a detected deviation exceeding a noise threshold, filtering the noisy measurement signal using the signal filter to determine an estimated state value, and determining that a disturbance has occurred in response to the estimated state value crossing a disturbance threshold. In some embodiments, the method further includes performing one or more control actions in response to the detection of a disturbance.
