Setting for single-phase operation
Note
On appliances with a single phase connection, set the
heat pump manager as follows for calculating the amount
of heat.

Material losses
!
Condensation caused by the temperature falling below
the dew point can lead to material losses. The appliance
is therefore approved exclusively for area cooling.
f When making the area cooling settings, observe the infor-
mation in the commissioning instructions for the heat pump
manager.

Recommended for two-pipe heating systems with radi-
ators to reduce flow noise at thermostatic valves
The pump reduces the delivery head by half when the
flow rate in the pipework decreases.
Saves energy by matching the delivery head to the flow
rate demand and the lower flow velocities.
Choice of three pre-defined curves (I, II, III).
Q/m³/ h
Recommended for underfloor heating systems, large
pipework or any application with a non-varying pipe-
work curve (e.g. cylinder charging pumps), as well as
single-pipe heating systems with radiators
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
Recommended for systems with unchanging system
resistance which require a constant throughput.
The pump runs at three preset fixed speed levels (I, II,
III).
Note
Factory setting: Constant speed,
Q/m³/ h curve III
Filling and venting the system correctly
If the pump does not vent 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.
Note
After venting, the LED indicator displays
the previously set pump values.
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).
