What became of getting your "electric only" function resolved for your water heater?

Have you found a way to separate your white and orange wires to gain the "electric only" feature by utilizing your existing indoor coach switches?

Simply hook the white "electric" wire directly to a 12 volt source- you will have to find power close to the heater to avoid running an extra wire.
This is about the only way to do it, as the heater uses the single thermostat and a relay, which must be used.
