10.3 Setting the bypass valve
Caution.
Risk of material damage caused by incor-
rect setting of the high-efficiency pump
If the pressure at the bypass valve is in-
creased (by turning it clockwise) and the
pump output is set to less than 100%, the
product may not operate correctly.
▶ In this case, set the pump output to
5 = 100% using diagnostics parameter
d.14.
1. Remove the front casing. (
