BAS Graphics USB contain a suite of Visio controls stencils and objects used to make graphics for HVAC systems. Each Visio stencil is made so that it fits and interacts with other stencils and objects in the library, without the need for rescaling. Eleven (11) VISIO stencils are provided with the BAS Graphics USB. Items include chillers, ahus, pipe, arrows, backgrounds and sensors. These graphics cover the basic needs for control system interfaces.
