5 Pump description
In an average household, 10 to 20% of electricity consumption is used by
conventional standard pumps. We have developed a circulation pump with
an energy efficiency index ≤ 0.20. By using Pulse Trade 25-60/130, energy
consumption can be reduced by up to approx. 80% compared to a
conventional circulation pump. The hydraulic capacity can be kept almost the
same as with the standard pumps. The pump capacity adapts to the actual
system demand as it works according to the proportional pressure method.
6 Pump settings and capacity
6.1 Buttons
All pump functions can be controlled with just two buttons. The button
switches the night reduction function on and off. The button controls the
operating modes. The selected operating mode is shown in the clear field of
the LED indicator.
6.1.1 Service mode, setting the capacity range
The capacity range can be changed to 4m or 6m in service mode.
The pump must be disconnected from the
230V mains voltage for at least 15 seconds.
Connect the pump to the 230V mains voltage.
Press the and buttons simultaneously
within 3 seconds.
Then release both buttons.
Select the capacity range with the button .
-4 = 4m
-6 = 6m
The pump must be disconnected from the
230V mains voltage for at least 15 seconds.
Connect the pump to the 230V mains voltage

5. Display for activated AUTO Smartadapt mode.
6. Display of the nine operating levels
(characteristics) of the pump.
6.3 Selection of the operating mode and degree of work
6.3.1 Constant speed adjustment I, II, III
In this operating mode, the pump runs at a constant rotational speed over the
entire characteristic curve.
6.3.2 Constant pressure adjustment CP 1, CP 2
In this type of adjustment, the pressure generated by the pump is kept at a
constant level. This type of adjustment is especially suitable for use in
underfloor heating systems.
6.3.3 Proportional pressure adjustment PP1, PP2
The pump is controlled by the proportional pressure method. In this case, the
pressure generated by the pump is adapted to the changing flow rate. This
operating mode is especially useful when the pump is to be used as a
circulation pump for heating.
6.3.4 Smartadapt
The Smartadapt AUTO function is designed for two-circuit heating systems
and underfloor heating systems. The pump capacity is automatically adjusted
to the actual heat demand of the installation. The pump power is adjusted
gradually and may take more than a week. If the power supply to the pump is

8.1 Recommendations for selecting a degree of work
Factory configuration = AUTO Smartadapt
8.2 Automatic night reduction of power
Conditions for automatic night reduction:
Pumps installed in gas boilers with low water capacity must never be set
to automatic night reduction.
If the heating system does not supply enough heat to the radiators,
check whether the automatic night reduction function is active. If
necessary, deactivate the automatic night reduction function.
To ensure that night reduction functions properly, the following requirements
must be met:
1. The pump must be installed on the supply
2. The heating system must be equipped with automatic temperature
adjustment on the supply.

13
How automatic night reduction works
Press the button to activate the night reduction function. If the adjacent
highlighted field is lit, the night reduction is activated and the pump
automatically switches between normal operation and night reduction.
Switching depends on the flow temperature.
The pump automatically switches to night temperature reduction if the flow
temperature drops by more than 10°-15°C in 1 hour.
Switching to normal operating mode takes place immediately as soon as the
flow temperature rises again by 3°C.
9 Filling and venting the installation
Fill and vent the installation properly. To vent the pump, the electronics
should be set to level III and operated in this position for at least 20 minutes.
Caution After this procedure, you can set the pump to the desired control
mode.
Incomplete venting will cause noise in the pump and system.
Warning! Danger of burns!
Depending on the operating status of the installation,
the entire pump can become very hot.
