Re: Hot Water Heater
I'm starting to think they're just extra switches.
The switch above the bed worked just like you said. I turned it on, I could hear the propane heater ignite, and the light went out (but the heater kept working). Tested hot water at sink. Almost hot but not quite. At least I know it's working.
So I shut off the propane and turned on the generator, and tried the 110V HWH switch. No hot water. Nothing. Then tried the 12V, with and without the generator. Nothing.
I started digging around under the sink and found 2 loose wires. I tested them with a 12V test light and sure enough, they get 12V power when the 12V switch is on. So it's wired for a 12V HWH but not equipped with one.
I have no idea about the 110V swithc. It lights up when I turn it on but I have no idea what it goes to. I thought maybe it controlled the outlet next to it, but that has 110V whether the switch is on or off.
