With its Onboard kWh Meter, Mulitpump/Fan Application. and Fire Mode features, the Siemens BT300 took their VFD portfolio to the next level of efficiency. The BT300 is well-suited for demanding HVAC environments and can deliver 20-50% of energy compared to equipment with little or no control. Built-in features – like a real-time clock, energy savings optimization programming, and a sleep function – help measure energy savings — and the BT300 VFDs are ready to communicate with Building Management Systems via embedded RS485 and Ethernet HVAC protocols: P1 protocol for APOGEE; BACnet MS/TP; Modbus RTU; Johnson Control – Metasys N2; and BACnet IP, Modbus TCP, Optional LON Interface. Well done Siemens!
