About this file
This document contains control diagrams and sequences of operation for a building automation system at a Department of Veterans Affairs medical facility. The diagrams specify control sequences for air handling units, variable air volume boxes, exhaust fans, pumps, boilers and other mechanical equipment. Sensors, controllers and other control components are shown along with their integration on the network. Points, alarms and interfaces are defined. This level of detail indicates the project involves retrofitting the existing HVAC and controls infrastructure with a new building management system to centralize monitoring and control of mechanical and electrical equipment.
