In the i-Vu® interface, select the controller in the navigation tree and go to Properties > BACnet Objects tab. When
an i-Vu® Open controller or a third party system writes to any of the system points, you must use BACnet Priority
Level 16 and the value must not be written to or refreshed more than once per minute (60 seconds).
CAUTION If any other Priority Level is used, the value will not be recognized by the controller.
* Modbus, N2, and LonWorks default values only apply to multi-protocol controllers.
† Points do not apply to multi-protocol controllers.
