8.2 Setting the pump output
The product is equipped with a speed-regulated high-effi-
ciency pump, which adjusts independently to the hydraulic
conditions of the heating installation.
If you have installed a low loss header in the heating install-
ation, you should switch off the speed regulation and set the
pump output to a fixed value.
▶
If required, change the setting of the pump speed, which
depends on the operating mode, under diagnostics code
d.14 .
