Abstract

A pump unit (2) has an electrical drive motor (5) and a control device (4) for controlling the drive motor (5), wherein said control device (4) includes at least one microprocessor (8) and storage means (6) which is able to store at least one control program executable by said microprocessor (8), wherein said control device (4) includes or communicates with a programming module (7) by which at least one user application can be created and/or modified and stored in said storage means, wherein said programming module (7) is designed such that at least one input parameter (13), at least one operator (10) and at least one action (14) can be chosen as program elements and combined to generate at least one user function (18) of said user application which can be executed by said microprocessor.

Claims

1-17. -17. (canceled)

18. A pump unit (2) having an electrical drive motor (5) and a control device (4) for controlling the drive motor (5), wherein said control device (4) comprises at least one microprocessor (8) and storage means (6) configured to store at least one control program executable by said microprocessor (8), wherein said control device (4) comprises or communicates with a programming module (7) by which at least one user application is created and/or modified and stored in said storage means, wherein said programming module (7) is designed such that at least one input parameter (13), at least one operator (10) and at least one action (14) are chosen as program elements and combined to generate at least one user function (18) of said user application which is executed by said microprocessor.

19. The pump unit according to claim 18, wherein the control device (4) with said microprocessor (8) and said storage means (6) are located in at least one electronic housing arranged at said drive motor (5) or in a housing of said drive motor (5).

20. The pump unit according to claim 19, wherein said programming module (7) is arranged in said at least one electronic housing.

21. The pump unit according to claim 18, wherein said programming module (7) forms a unit separated from the other parts of said control device (4) and connected with said control device via a data interface.

22. The pump unit according to claim 21, wherein said data interface comprises a network connection.

23. The pump unit according to claim 22, wherein the network connection is an internet connection (44).

24. The pump unit according to claim 18, wherein said programming module (7) is a software module.

25. The pump unit according to claim 18, wherein said programming module (7) is designed such that several input parameters (13), several operators (10) and/or several actions (14) of said drive motor (5) can be chosen as program elements and combined to generate at least one user function (18) of said user application.

26. The pump unit according to claim 18, wherein said programming module (7) is designed such that at least one action of an external device can be chosen as a program element.

27. The pump unit according to claim 18, wherein said programming module (7) is designed such that at least one action of the drive motor or a further user function can be chosen as program elements.

28. The pump unit according to claim 18, wherein said at least one input parameter (13) is provided by at least one sensor arranged in said pump unit, at least one external sensor, a computing device, data storage means and/or a data network.

29. The pump unit according to claim 18, wherein the actions (14) of said drive motor (5) comprise a switching on and off and/or a speed adjustment of said drive motor (5).

30. The pump unit according to claim 18, wherein said programming module (7) comprises at least one display (30) and at least one input device (28).

31. The pump unit according to claim 30, wherein said programming module comprises at least one display (30) showing several program elements which can be chosen and combined for creating at least one user function (18) of said user application.

32. The pump unit according to claim 30, wherein said display (30) is a touch screen display and acts as an input device.

33. The pump unit according to claim 18, wherein said programming module (7) is designed such that program functions can be stored manually or automatically from an external storage means or a data network into said storage means (6).

34. The pump unit according to claim 18, wherein the programming module (7) is designed such that it may communicate with an external device to change settings of said device.

35. The pump unit according to claim 18, wherein said pump unit (2) is a recirculation pump.
