Selection of the operating mode and operating level

1. Constant speed mode I, II and III
In this operating mode, the pump rotates at a constant speed over the entire characteristic
curve.
2. Constant pressure mode CP 1, CP 2, CP 3
In this control mode, the pressure generated by the pump is kept at a constant level.
This control mode is particularly suitable for use in underfloor heating systems.
3. Proportional pressure mode PP1, PP2, PP3
In this mode the pump is controlled according to proportional-pressure principle.
In this case, the pressure generated by the pump adapts to the changing flow rate.
This operating mode is particularly suitable if the pump is intended for use as a heating
circulation pump.
4. AUTO Smart Adapt
The AUTO Smart Adapt function is designed for two-circuit heating systems and underfloor
heating systems. In this mode the pump performance adapts automatically to the actual heat
demand of the system. The adjustment of the pump performance happens gradually and can
take longer then a week. If the power supply to the pump in interrupted, the pump saves the
last settings and resumes the adjustment as soon as the power supply is restored.
