What are these three switches for?
Since I've owned this motorhome I've always assumed these three switches were related to my Oasis Hydronic heating system. Today I realized they have no affect on the heating system nor the domestic water system. With the black switch toggled on, I can see a momentary lighting of my gen start button and a draw on my main inverter of over 30 amps for as long as I hold the button down. The red button on the left is an on/off button and if it is turned on I recognize a draw on the main inverter of over 8 amps. The red button on the right shows a 2 amp draw when turned on. It almost appears to be a battery parallel button, however my house batteries are not tied into my chassis batteries. This set up is on a 2009 Silver Crown SC45.
I have left the buttons off for now until I can track down their purpose.
