A system and approach for providing information about a heating, ventilation and air conditioning system. A screen of the system on a display may have a portion revealing a perspective with a view of components such as cooling and heating coils, fans, dampers, sensors, and so forth. Data modules may be shown proximate to the components on the screen and indicate certain parameters about them. As second portion of the screen may show control and information modules related to items such as temperature and pressure control, and operating mode. The screen may also reveal relationships among sub-systems, applications, zones, alarms, and other items.
