SUPERVISORY CONTROLLER

MD20

Master Display

The Master Display (MD20) is a supervisory controller of the Facility Explorer system.

The Master Display monitors and interacts with a network of Heating, Ventilating, Air Conditioning, and Refrigeration (HVACR) controllers to form a complete building or equipment control system and provides operating data to local and remote users and operators via a number of different media options. The device has an integral graphic display along with a number of operating keys and indicators that present data to the user in a standard or customized way to view and acknowledge alarms, display historical trend data, and to override the operation of the monitored equipment. An embedded Web server enables you to access data from a Web browser by telephone line and modem or by direct connection to the Master Display. You can view current operating data, including active alarms, as well as trend logs and the event history file. You can also acknowledge alarms and send commands to the controlling devices using the user identification and password control on the Web page.

The Master Display can also send alarm messages by e-mail, by Short Message Service (SMS) to a mobile telephone, by fax, and to a printer for a local record of events as they occur. The Master Display is freely programmable using the FX Tools Pro software package and the functions include centralized control and management of distributed applications as well as the display and communication features.
