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.
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.
For wiring details, see the topic Application drawings on page 41.
