The ASIC/3-6115-ETH Dual-Ethernet Airflow Controller from ASI Controls is a powerful, fully programmable VAV controller designed for modern building automation networks. Combining advanced airflow control with an integrated dual-port Ethernet switch, the 6115-ETH simplifies network design while delivering precise, scalable HVAC control for commercial applications.
Engineered for BACnet/IP and legacy RS-485 networks, this controller offers the flexibility to integrate into both new construction and retrofit projects. With object-based programming, multiple I/O options, and compact VAV-ready construction, the 6115-ETH is a versatile solution for today’s intelligent buildings.
Built for Modern BAS Networks
One of the defining features of the ASIC/3-6115-ETH is its integrated dual-port managed Ethernet switch. This allows controllers to be daisy-chained directly using standard CAT5/6 cabling, eliminating the need for external Ethernet switches at the device level. The result is a cleaner network layout, reduced hardware costs, and faster installation.
The controller supports both BACnet/IP over Ethernet and RS-485 (BACnet MS/TP or ASI legacy protocol), making it ideal for mixed-network environments. This dual-communication flexibility allows the 6115-ETH to seamlessly bridge older systems with modern IP-based architectures.
