BACNET CONNECTION AND SETTINGS

BACnetis a standard communication protocol for Building Automation and Control (BAC) networks that can be used to monitor and control Komfovent air handling units with C6 controller. The supported Data Link Layer is BACnet / IP. BACnet protocol works via Ethernet interface, connection is provided to RJ-45 socket (Pic.1) on the C6 controller (CAT5 cable is recommended):

Below is default network settings of the C6 controller. These can be changed according to the building network software requirements.
To do so, it is needed to connect a laptop to the integrated webserver of C6 controller:

Picture 2. Connectivity settings

C6 controller IP can also be viewed and changed on the control panel – from Main menu go to Advanced settings- >Connectivity:
