Abstract

The invention relates to 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) which is able 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 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.

Description

technical field [0001] The invention relates to a pump unit according to the introductory part of claim 1 . Background technique [0002] Many modern pumps are provided with different types of controls to control the pump in a specific way. Circulation pumps are often intentionally made to provide specific head and flow rates under specific circumstances in order to meet current demands. In order to meet different requirements, prior art pumps can be controlled according to different control modes integrated in the pump control. Pump control can be adjusted by changing one or more parameters. This can be achieved by the user of the pump by using an input device provided on the pump itself, such as a switch, or via an interface to an external control device. [0003] With such prior art pumps it is difficult to adjust the pump to all the different requirements of the different uses. Contents of the invention [0004] It is therefore an object of the present invention to...
