  • By schedule – to shut off the water at a certain time
  • By security mode change – in case of arming or disarming
  • Upon pressing LightSwitch, for example, when the last employee leaves the office premises.
  • By pressing Button – for manually shutting off water in the event of an emergency
  • By temperature – to shut off water in the heating pipes for winter.
