How does it work?
The S7-1200 controller starts the irrigation of the individual zones once a day at a specified time for a previously set time period. The zones are watered one after the other. You can manipulate the program sequence (manual operation) via a web browser (e.g. on a smartphone) or by using a Touch Panel. The water is either taken from a water tank using a pump or from the public water supply. The water tank can be monitored with the help of a level sensor.
