Diagnosing Alarms With The Meter Map

If your Morningstar controller’s meter is displaying an alarm, it is helpful to consult the meter map for the particular controller you are using in order to access additional helpful information.  The arrows on the map correspond to the arrow buttons on your meter, and the sequence that they need to be pressed in order to display the diagnosis.  If you did not save the meter map that came with your controller, you can access it on the Morningstar Support site.
