Commissioning

12. Commissioning
Our customer support can assist with commissioning, which is a
chargeable service.
If the appliance is intended for commercial use, observe the rules
of the relevant Health & Safety at Work Act during commissioning.
For further details, check with your local authorising body (in
Germany, for example, this is the TÜV).

LED indicators
Operation indicator:
LED illuminates green in normal operation
LED illuminates/flashes when there is a fault
Display of selected control mode
∆p-v, ∆p-c and constant speed
Display of selected curve (I, II, III) within the control
mode
Combinations of LED displays for venting function, man-
ual re-start and key lock
Operating button
Press
To select control mode
To select curve (I, II, III) within the control mode
Press and hold
To activate venting function (press for 3 seconds)
For manual restart (press for 5 seconds)
To lock/unlock keys (press for 8 seconds)
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
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

The control system keeps the set delivery head con-

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

Q/m³/ h
Constant speed (I, Recommended for systems with unchanging system
II, III) resistance which require a constant throughput.
H/m The pump runs at three preset fixed speed levels (I, II,

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

sec
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).
