BACNET CONNECTION C8
INSTALLATION AND SERVICE MANUAL
BACNET CONNECTION AND SETTINGS
BACnet is a standard communication protocol for Building Automation and Control (BAC) networks that can be used to monitor and control Komfovent air handling units with C8 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 C8 controller (CAT5 cable is recommended):
Below is default network settings of the C8 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 C8 controller:
Picture 2. Connectivity settings
To have a stable connection between BMS and AHU via BACnet network, at least 1s. polling time is recommended.
C8 controller IP can also be viewed and changed on the control panel – from Main menu go to Advanced settings>Connectivity:
