Devices, methods, and systems for determining the cause of a fault in a heating, ventilation, and air conditioning (HVAC) system are described herein. One device includes a memory, and a processor configured to execute executable instructions stored in the memory to receive operational data associated with an HVAC system, receive control logic associated with a controller of the HVAC system, determine a cause of a fault occurring in the HVAC system based, at least in part, on the operational data associated with the HVAC system and the control logic of the controller of the HVAC system, and provide the cause of the fault occurring in the HVAC system to a user.

Method and system for determining a cause of a fault in a building control system

A first image of an electronic device is captured and processed in order to identify the electronic device. After identifying the electronic device, information is downloaded to a mobile device including specific wiring instructions for connecting the electronic device, which are superimposed onto an image of the electronic device to guide a user of the mobile device in wiring the electronic device. A second image of an at least partially wired electronic device may be captured and processed to ascertain whether there are any wiring errors. When wiring errors are found by the remote server, the mobile device receives a message from the remote server indicating the wiring errors that were found.

Using augmented reality to assist in device installation

A tool for an approach and mechanism for calculating and configuring memory mapping of trend log objects in a system, such as an HVAC. It may incorporate determining available memory of a controller for trending a unit of equipment of a system. A calculation of available records may be made for configuring and using a trend. The calculation may be made in view of the controller memory and parameters including buffer size, log interval and retention time. A change in parameters may cause a recalculation of available records. The 'available record' terms may be regarded as being in a user-understandable format. The format may be intuitive. Anomalies of trends of equipment may lead to spotting issues of the equipment.

Determining the cause of a fault in an HVAC system

Validating a task being performed on an HVAC system is described herein. One system includes a plurality of control devices associated with a heating, ventilation, and air conditioning (HVAC) system, wherein each respective control device is configured to record an action, taken by that control device as part of a task being performed on the HVAC system, as a block in a block chain for the task, send the block to the other control devices for validation of the action in the block chain for the task, update, upon the validation of the recorded action, the block chain for the task with the block having the recorded action, and store the updated block chain for the task.
