Every once and a while our 2011 Journey display gets confused.
Found a reset process for One Place Monitor panel.
To Reset the Panel to Default
1.Press and hold all three buttons shown above (no picture here; so press Water Pump, Tank Level and Battery Level) for approximately 6 seconds, until the screen resets.
2. Press the Default Button (Water Pump)
3. Press the Exit Button (Battery Level).
4. The Panel will return to the Water Pump Display.
Not sure if your display is like mine.
