Location in the menu: P3.21.2.1
Use this parameter to control the Jockey pump function. A Jockey pump is a smaller pump that keeps the pressure in the pipeline,
when the main pump is in the sleep mode. It can occur, for example, in the night.
The Jockey pump function controls a jockey pump with a digital output signal. A jockey pump can be used if a PID controller is used
to control the main pump. The function has 3 operation modes.
