Modern buildings demand real-time HVAC control to balance energy efficiency and occupant comfort. Traditional systems face:
Limited interoperability with mixed-protocol devices.
High maintenance costs due to on-site troubleshooting.
Rigid architectures unable to adapt to dynamic needs.
The BA190 acts as a multifunctional gateway between HVAC equipment (chillers, VAVs, sensors) and building management systems (BMS). Key features deployed:
BACnet/IP Integration: Unified communication with BMS (e.g., Siemens Desigo, Johnson Controls Metasys).
Web-Based Logic Control: Custom rules (e.g., temperature setpoints, occupancy-based airflow) via built-in PLC.
Remote Monitoring: Cloud-connected diagnostics reduced maintenance visits by 40%.
Flexible I/O Expansion: Supported analog (4–20mA) and digital signals for diverse sensors.
Retrofitted 20-floor office building in Singapore.
Connected 150+ devices (thermostats, CO₂ sensors, actuators) via BA190’s RS485 Modbus-to-BACnet/IP conversion.
Automated demand-controlled ventilation using occupancy data.
30% Energy Savings: Dynamic load matching cut HVAC power consumption.
Faster Fault Resolution: Remote alerts for filter clogs or valve failures.
Scalability: Added solar monitoring via MQTT without hardware changes.
Why This Matters
The BA190 bridges legacy systems and IoT, making it ideal for:
Smart Offices
Green Buildings (LEED Certification)
Hospital Air Quality Control
