The displays are available in various colors.
If you know how to use a voltage meter you can check the house battery voltage with your rv disconnected from the ac electrical source.
That leaves our heater with 110 volts on the bottom feed and 10 volts on the top feed.
Compare that to a battery voltage reading with the power back on and the power converter operating.
