BACnet objects

The SimplyVAV controllers are BACnet Application Specific Controller (ASC) that are
composed of standard BACnet objects. This section lists the objects that are likely to be
monitored by a standard BACnet operator workstation to verify system operation.

Caution

Changing the configuration of any object may result in
unpredictable operation of a controller and damage to
equipment that is under control of a SimplyVAV controller.

Input objects

The following BACnet input objects represent values at the physical inputs of the controller.
