The P3 Series pumps offer nine automatic operation modes and can be installed in any domestic heating system. The control panel's location allows for easy installation in concealed spaces.
- AUTO Mode: Activated by pressing a single button, with automation adjusting the pump's operating range to suit the current heating system.
- Two Constant Pressure Modes (CP1 and CP2): These modes maintain consistent pressure regardless of flow rate.
- Two Proportional Pressure Modes (PP1 and PP2): The pump adjusts its operation in response to pressure differences, proportionate to the flow rate.
- Three Fixed Speeds ("Old School"): Selectable via a single button, offering full power range utilisation.
- Automatic Night Power Reduction Function: Reduces energy consumption to 5 watts without compromising heating quality.
ELECTRICAL AND THERMAL PROTECTION: These safety systems prevent pump breakdown due to external factors unrelated to the pump's operation.
