Selection of the operating mode and operating level
1. Constant speed control I, II and III
In this operating mode the pump operates at constant rotational speed over the entire
characteristic curve.
2. Constant pressure control CP 1, CP2
In this control mode the pressure generated by the pump is kept constant.
This control mode is particularly suitable for use in underfloor heating systems.
3. Proportional pressure control PP1, PP2
The pump is controlled according to the 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 as a heating circulation
pump.
4. AUTO Smart Adapt
The AUTO Smart Adapt function is intended 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 power adjustment of the pump is gradual and can take longer
than a week. If the power supply to the pump is interrupted, the pump saves the last setting
and resumes the adjustment as soon as the power supply is restored.
On delivery, the pump is set to the AUTO Smart Adapt operating level. By repeatedly briefly
pressing of the selection button, the operating modes: constant speed, constant pressure,
proportional pressure and AUTO Smart Adapt are switched through continously. The selected
operating mode is indicated by the coressponding LED with characteristic symbols.
