This article shows system integrators how the BA190Pro HVAC system control module uses RS485, dual Ethernet, and flexible I/O boards to acquire HVAC data (temperature, CO₂, fan status, valve position, energy) and execute local edge logic (VAV PID, IAQ interlocking, fault diagnosis). It then seamlessly connects to BMS or cloud via BACnet/IP, MQTT, Modbus TCP, and OPC UA – enabling low‑cost, high‑efficiency project delivery.
