The P2 Series pumps feature nine built-in automatic operation modes. Their intelligent operation adjusts to the heating system's specifications, ensuring optimal comfort and energy efficiency.
- AUTO Mode: Activated by pressing a single button, suitable for 80% of existing heating systems.
- Two Constant Pressure Modes (CP1 and CP2): These modes maintain constant pressure in heating systems regardless of the flow rate.
- Two Proportional Pressure Modes (PP1 and PP2): These modes adjust pump operation proportionally to pressure changes in the system.
- Three Fixed Speeds ("Old School"): Selectable via a single button, allowing full use of the pump's power range.
- Night Operating Mode: Reduces energy consumption to 5 watts while maintaining heating system quality.
ELECTRICAL AND THERMAL PROTECTION: These safety systems prevent pump breakdown due to external factors unrelated to the pump's operation.
