Selection of the operating mode and degree of work
1. Constant speed adjustment I, II i III
In this operating mode, the pump runs at a constant rotational speed over the entire
characteristic curve.
2. Constant pressure adjustment CP 1, CP 2
In this type of adjustment, the pressure generated by the pump is kept at a constant level.
This type of adjustment is especially suitable for use in underfloor heating systems.
3. Proportional pressure adjustment PP1, PP2
The pump is controlled by the proportional pressure method. In this case, the pressure
generated by the pump is adapted to the changing flow rate. This operating mode is
especially useful when the pump is to be used as a circulation pump for heating.
4. Smartadapt
The Smartadapt AUTO function is designed for two-circuit heating systems and underfloor
heating systems. The pump capacity is automatically adjusted to the actual heat demand of
the installation. The pump power is adjusted gradually and may take more than a week. If the
power supply to the pump is interrupted, the pump remembers the last setting and resumes
adjusting as soon as power is restored.
Upon delivery, the pump is set to the AUTO Smartadapt operating level. Multiple brief pressing
the select button will continuously toggle between the constant speed, constant pressure, pro-
portional pressure and AUTO Smartadapt modes.
The selected operating mode is indicated by the appropriate LED with characteristic symbols.
