8.8 Setting the pump output
Applicability: Germany
The product is equipped with a speed-regulated high-effi-
ciency pump, which adjusts independently to the hydraulic
conditions of the heating installation.
If required, you can manually set the pump output to five
fixed, selectable steps based on the maximum possible out-
put. This switches the speed regulation off.
The pump operating mode is set to "auto" at the factory in
accordance with the most recent energy conservation ordin-
ance.
▶
To change the pump output, change D.014 to the desired
value.
Note
If you have installed a low loss header in the
heating installation, we recommend switching
off the speed regulation and setting the pump
output to a fixed value.
