A method of providing a plurality of controller certificates for a plurality of controllers within a Building Management System (BMS) includes downloading project information defining the BMS and using the downloaded project information to solicit a Certificate Signing Request (CSR) from each of the plurality of controllers of the BMS. The received CSRs are uploaded to a remote server so that the remote server can generate a corresponding controller certificate for each of the plurality of controllers of the BMS. The generated controller certificates are then downloaded to the corresponding one of the plurality of controllers of the BMS.

Managing certificates in a building management system

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.

Devices and methods for airflow and water balancing are described herein. For example, one or more embodiments include receiving, with a balancing handler, a signal that includes a variable air volume (VAV) balancing command for multiple VAV controllers; determining VAV balancing profiles associated with each of the multiple VAV controllers; and sending the VAV balancing command to the multiple VAV controllers in accordance with the VAV balancing profiles.
