Any other value is kept constant.
Use this control mode if you want to control a value
which is not available in the Control mode menu.
Connect a sensor measuring the controlled value to
one of the analog inputs of the pump. The controlled
value will be shown in percentage of sensor range.

17.6.11 Constant curve
Pump variant
TPE3, TPE3 D
TPE2, TPE2 D
You can set the pump to operate according to a
constant curve, like an uncontrolled pump. See the
figure Constant curve.
You can set the desired speed in % of maximum
speed in the range from 13 to 100 %.
H
Constant curve
Depending on the system characteristic and the duty
point, the 100 % setting may be slightly smaller than
the actual maximum curve of the pump even though
the display shows 100 %. This is due to the power
and pressure limitations built into the pump. The
deviation varies according to pump type and pressure
loss in the pipes.
