The S on the water heater switch stands for Suburban, the brand of water heater you likely have. That switch is to turn on the Direct Spark Ignitor for your propane to ignite. The DSI takes the place of a pilot light. This may help you understand it better:
That other switch is most likely the water pump switch, as others have stated. It could also be a switch to turn on the electric heating element in your water heater, again explained in the above link. If so, do not flip it on without water being in the heater.
I would bet it's for the water pump though. You would only use the water pump when not hooked to a city water connection, and had placed water into your onboard fresh water tank. You would then need to turn the pump on to be able to pump the water out of your tank, and to your faucets when using them.
Is that switch in the on position currently?
