10.1.2.1 Pump mode setting
The product is equipped with a stage-controlled high-effi-
ciency pump. In the automatic operating mode (d.14 = 0),
the pump stage is regulated in such a way that a constantly
available pressure is guaranteed.
If required, you can manually set the pump mode to five
fixed, selectable stages based on the maximum possible out-
put. This switches the speed regulation off.
▶ To convert the pump output, change d.14 to the desired
value.
