Advanced Features

• eLink™ Connectivity: Utilizes NFC technology for access to product specs, technical documentation, instruction manuals, and support information via smartphone.
• SelfSensing Series with ProBalance®:
  • Integrated pump and drive for automatic response to system demand changes.
  • No remote sensors or complex wiring required for system balancing.
  • Multiple operating modes: Constant flow, Constant pressure, Flow compensation, Duplex pump alternation.
  • Provides automatic alerts with optional shutdown for no-flow, dry-run, and end-of-curve operation.
  • Enables "Do-It-Yourself" balancing, reducing contractor costs and installation time.
  • Note: ProBalance® feature is not available in Parallel Pumping Configuration.
• Parallel Pumping Configuration:
  • SelfSensing Modulating Pump Controller (MPC) stages 2 to 4 pumps in parallel for optimized efficiency.
  • Sensorless Parallel Pump Controller provides single building automation systems connection (BACnet MSTP or Modbus RTU).
