Moving Beyond MSTP: Rethinking AHU Controls for Modern Buildings
white paper
Modern air handling units demand more than legacy communication networks can support. As systems become more data-driven, BACnet MSTP can create limitations in speed, scalability, and visibility.
BACnet/IP leverages standard Ethernet infrastructure to enable faster data exchange, real-time performance insight, and seamless integration with modern building systems.
The result: better system responsiveness, improved energy optimization, and a future-ready control architecture.
