BACnet IP/MSTP VAV Controller - INSTALLATION
INSTRUCTION
NETWORK SECURITY
WARNING
Honeywell hereby expressly states that the BACnet
IP/MSTP VAV controller is not inherently protected
against cyber-attacks from the Internet and that it is
therefore intended solely for use in private, protected
networks.
Unprotected Internet connections can expose the BACnet
IP/MSTP VAV controller to cyber-attacks from third parties who
can then damage it and connected facility components or cause
them to malfunction, or who can misuse it for illegal purposes
for which the operator may then be held liable. When directly
connected to the Internet, the BACnet IP/MSTP VAV controller
automatically becomes a potential target for cyber- attacks. To
ensure safe and reliable operation take necessary protective
measures. If it is not necessary for the BACnet IP/MSTP VAV
controller to be accessible from the Internet, it should be isolated
from the Internet via a suitable firewall.
If it is necessary for the BACnet IP/MSTP VAV controller to be
accessible from the Internet (e.g., to perform a remote
maintenance), the use of a coded VPN connection is
indispensable. Suitable VPN routers are available from
numerous third-party manufacturers in a wide variety of
designs, for operation at 230 V or 24 V.
