Setting the pump output
The product is equipped with a speed-regulated high-effi-

conditions of the heating installation.
If you have installed a low loss header in the heating install-

setting the pump output to a fixed value.

If required, change the setting for the pump speed, which
depends on the operating mode, using diagnostics code
