The P5 Series Pumps are designed for HVAC applications, including boilers, heat pumps, and HIUs. They feature two unique PWM functions (GT and ST) for remote control via two low-voltage control cables, compatible with any controllers/thermostats like Siemens, Honeywell, and many more.
These pumps offer 10 automatic operation modes and are compatible with any domestic heating system:
- AUTO Mode: Activated by pressing one button, suitable for 80% of existing heating systems.
- Two Constant Pressure Modes (CP1 and CP2): Ideal for underfloor heating and systems with minimal flow rate changes.
- Two Proportional Pressure Modes (PP1 and PP2): Suitable for systems with significant flow rate changes.
- Three Fixed Speeds ("Old School"): Selectable with one button for full power range use.
- Automatic Night Power Reduction Function: Reduces energy consumption to 5 watts without affecting heating quality.
ELECTRICAL AND THERMAL PROTECTION: These safety systems prevent pump breakdown due to external factors unrelated to the pump's operation.
