L
Fig. 32 Constant level
11.4.7 Constant other value
Any other value is kept constant.
11.4.8 Constant curve
The pump can be set to operate according to a constant curve,
like an uncontrolled pump. See fig. 33.
The desired speed can be set in % of maximum speed in the
range from 25 to 100 % (110 %).
