The P7 Series Pumps are designed for commercial use, featuring motors that utilise permanent magnet and compact rotor technology for quiet operation and low power consumption. These pumps offer 13 automatic operation modes.
- AUTO Mode: Activated by pressing one button, suitable for 80% of existing heating systems.
- Four Constant Pressure Modes (CP2, CP3, CP4, CP5): Ideal for underfloor heating and systems with minimal flow rate changes.
- Four Proportional Pressure Modes (PP2, PP3, PP4, PP5): Suitable for systems with significant flow rate changes.
- Four Constant Rotor Speed Modes ("Old School"): Switchable with one button for consistent rotor speed operation.
- Automatic Night Power Reduction Function: Reduces energy consumption to 5 watts without affecting heating quality.
- Self-Ventilated Design: The pump casing is designed to prevent air ingress.
ELECTRICAL AND THERMAL PROTECTION: These safety systems prevent pump breakdown due to external factors unrelated to the pump's operation.
