glycol mixture at a mixing ratio of 1:1. If glycol is added, the
delivery data of the pump must be corrected according to the
higher viscosity, depending on the mixing ratio percentage.
Intended use of the pump/installation also includes follow-
ing these instructions.
Any other use is not regarded as intended use.

Product description

The pump (Fig. 1/1) consists of a hydraulic system, a glan-
dless pump motor with a permanent magnet rotor, and an
electronic control module with an integrated frequency con-
verter.
The control module has an operating knob together with an
LED display (Fig. 1/2) for setting all parameters and for dis-
playing the current power consumption in W.
3.3 Functions
All functions can be set, activated or deactivated using the
operating knob.
In the operating mode, the current power consumption in W
is displayed.
When the knob is turned, the LED display shows the deliv-
ery head in "m"
Control modes
Variable differential pressure (∆p-v):
The differential-pressure setpoint H is increased linearly
over the permitted volume flow range between ½H and H
(Fig. 2a). The differential pressure generated by the pump
is adjusted to the corresponding differential-pressure set-
point.
