Control modes and functions
Variable differential
Recommended for two-pipe heating systems with radi-
pressure ∆p-v
ators to reduce flow noise at thermostatic valves
(I, II, III)
The pump reduces the delivery head by a half when the
H/m
flow rate drops in pipework.
Saves energy by matching the delivery head to the flow

rate demand and the lower flow velocities.
I
Choice of three pre-defined curves (I, II, III).
Q/m³/ h
Constant pressure
Recommended for underfloor heating systems or with
differential ∆p-c
large-diameter pipework and for all applications with
(I, II, III)
a non-varying pipework curve (e.g. cylinder charging
pumps) and single-pipe heating systems with radiators
H/m
III
The control system keeps the set delivery head con-

stant, irrespective of delivered flow rate.
Choice of three pre-defined curves (I, II, III).

Venting
Fill the system properly and ventilate it
If the pump is not ventilated automatically:
Activate venting function via the operating button:
Press for 3 seconds then release.
Venting function starts (duration 10 minutes).
The top and bottom rows of LEDs flash alternately every
second.

sec
To cancel, press the operating button for 3 seconds.
Note
After venting, the LED indicator displays
the previously set pump values.

Setting control modes
Selecting the control
mode
The LEDs for the control modes and associated curves
illuminate one after the other.
Briefly press the operating button (for approx. 1 sec-
ond).
LEDs indicate the current selected control mode and
curve (see following table).
