  Average energy savings of up to 50% compared to a fixed-speed in-line pump
  Optimisation of the pump's duty point
• Easy installation
  A single button for choosing functions and adjusting setpoints
  Identical command and control interface on the entire range of variable-speed pumps
  Pump parameters displayed on an LCD screen
• Easy maintenance
  Fully automatic, maintenance-free operation
  Non-volatile memory: protection of setpoints and data storage in the event of a power cut
  Display of operating information and error codes on LCD screen
• Pump protection
  Integral thermal protection via a PTC temperature sensor
  IP 54 protection class for electrical parts of the motor and the electronic module
  Corrosion-resistant cataphoretic coating
• Acoustic comfort
  As the motor's speed is automatically adapted to the system's needs, noise levels are reduced at the terminals and pump
