  • Page 3 Description of Pump Frofiles a) INTERNAL CONTROL - Proportional pressure • Head (pressure): reduced with growing system pressure drop and increased with sinking system pressure drop (typically e.g. opening / closing of thermostatic heads) • Pump operating point: moves up or down on the selected proportional pressure curve depending on the current system pressure drop.
  • Page 4 e) EXTERNAL CONTROL - PWM A (heating) • The pump runs on a curve of constant speed depending on the current PWM value. • The speed slows down when the PWM value rises. If PWM equals 0, the pump runs at its max.
  • Page 5 DISPLAY CONTROL MODE green LED FLASHING EXTERNAL PWM C PWM A GREEN LEDS FLASHING CONTROL PWM SIGNAL RECEPTION FREQUENCY Not flashing Internal 1 flash per second External 12 flashes per second External WARNING: LEDs may be turned by 90° or 180°, or mirrored, depending on the specific pump type. When switched on, the pump runs at factory settings or the last setting.
