BACNET CONNECTION C5
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 C5 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 C5 controller (CAT5 cable is recommended):
Below is default network settings of the C5 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 C5 controller:
C5 controller IP can also be viewed and changed on the control panel – from Main menu go to Settings>Air handling unit->Connectivity:
