8.3. Window „Fan“

In this window you are able to choose whether the fan shall be regulated

manually or automatically into dependence of a temperature and further

parameters. At the manual setting activate the "manual power adjustment"

and simply use the slider to adjust the power while for the option "temperature

control" the temperature of the external temperature sensor or the internal

water temperature sensor is used for an automatic regulation. You can

choose freely which sensor should be used for the regulation.

You can influence all parameters by hand which are connected with the

automatic fan regulation in the field temperature regulator. Inexperienced

users can alternatively choose one of the predefined profiles.

On the right side two scales gives information about the output voltage of the

fan header as well as the adjusted power. Moreover, the currently measured

speed of the fan is displayed under the scale.

8.4. Windows „Pump and flow rate settings“

Here you can select whether the pump shall be controlled automatically or

manually.

At the "automatic frequency settings" the frequency of the pump is

automatically set to the highest possible frequency. To this the electronics of

the pump determines permanently the position of the rotor, current

consumption, performance as well as the voltage and calculates the optimal

operating point out of this independently. To this is the frequency repeatedly

tries to get as high as possible at a stable operation. Depending on the

resistance of a system the frequency of the pumps reaches approx. 75 - 85

Hz in a normal loop.

You can adjust the pump frequency manually at the "manual frequency

settings". If the chosen value is not attainable, then the pump tries to adjust

the highest possible frequency (below your target frequency) like in the case

of the automatic frequency setting.

With the button "reset maximum pump frequency" the maximum frequency

found out currently is rejected in the automatic and in the manual mode and

the pump tries once more to find the maximum frequency.

This process also can be automated by activating that the frequency shall be

reset automatically after X minutes.

The automatic deaeration of the pump can be actievated through the option

"activate deaeration mode". In the delivery state the deaeration by jumper is

predefined as described at the beginning. To be able to start the deaeration
