Application 2897 Slave Mode
Application 2897 is the slave mode application for the BACnet ATEC (see Ordering Notes [ 9] for product numbers). Slave mode is the default application that comes up when power is first applied to the controller. Slave mode provides no control. Its purpose is to allow the operator to perform equipment checkout before a control application is put into effect and to set some basic controller parameters (CTLR ADDRESS, APPLICATION, etc.). A controller in default state can also be used as a point extension device by unbundling spare I/O points at the field panel.
Using Auxiliary Points
It is possible to have extra points available on a BACnet VAV Controller — Electronic Output in addition to the ones used by the current application that is running in the controller. If these extra points are to be controlled by a field panel, then they must be unbundled at the field panel.
Using the Controller as a Point Extension Device
If the controller is only used as a point extension device, with no control application in affect, its application must be set to slave mode and points must be unbundled at the field panel. All points must be controlled from the field panel in order to be used.
