setup, transfer controls, alarms, events, status, and measurements.
Changes to controls or parameters must be made from the touchscreen display; they cannot be changed
remotely from a Building Management System (BMS) or from a web browser. (The BMS can issue dry contact
control signals, such as Remote EPO or Remote Source Select.)
