    5.5 Sequence of Operations All control equipment shall operate in stand-alone mode according to its sequence of operation in the absence of the Virtual Wall Controller. Occupancy WebCTRL® shall centrally coordinate the monitoring and control of all equipment. WebCTRL® allows the user to create plant wide schedules, trend graphs, and reports as well as adjust heating setpoints, pressure control, cooling and more.

    A custom, interactive plant layout graphic is included with the Virtual Wall system. This graphic displays the comfort level within each zone of the plant as well as a link to specific area graphics. Color coding of zones is relative to the setpoint; therefore, multiple regions of the same color may be different temperatures.
