Question about Gardena 4000 Silent

The Gardena 4000 Silent (garden pump) does not have an integrated automatic start/stop function. There is no indication that this model has an automatic start/stop function. Automatic controls are possible on other models with an electronic pressure switch, but not as standard on the 4000 Silent. For automatic functions, an electronic pressure switch would have to be retrofitted, which is not explicitly mentioned for this model.
