When an MV Override (MVO) status alert occurs, it means that the controller’s irrigation is being paused by a Master Valve Override. The controller will stop all irrigation until the master valve override duration has expired.
If you need to clear this alert, you will need to stop the Master Valve Override from the controller or from WeatherTRAK Central.

You can also stop the master valve override from WeatherTRAK mobile. For more information read: Creating, Canceling and Setting a Master Valve Override.
