3.3 Functions
All functions can be set, activated, or deactivated using the
operating button.
When in operating mode, the current power consumption in
W is displayed.
When the button is turned, the LED display shows the deliv-
ery head in “m”
or the speed stage.
Control modes
Variable differential pressure (Δp-v):
If the volume flow in the pipe network decreases, the pump
reduces the delivery head by half (Fig. 2a).
Constant differential pressure (Δp-c):
The control keeps the set delivery head constant irrespec-
tive of the volume flow delivered (Fig. 2b).
3 speed stages (c1, c2, c3):
The pump runs uncontrolled in three prescribed fixed speed
stages (Fig. 2c).
