Technical hardware details

The updated EVN230 household display and VertoMobile app

Our new household display includes major new features

Water consumption readings for cold and hot water

Two advanced "TRIP measurement" features

  • TRIP1: Resettable reading display that shows overall consumption readings
    • This feature enables residents to monitor their overall consumption over specific periods such as a day, week or month
  • TRIP2: Resettable reading display that shows overall consumption readings as well as the time for which water is used
    • This feature enables residents to monitor the amount of water and time used for activities such as taking a shower.

Flow display

  • This feature enables the user to set the flow rates of water outlets in the home (view: l/min)

VertoMobile login details

  • Residents can log in to the VertoMobile app using the login details shown on the household display
