Learning my new FSX 178BHSKX

[John 13aker]

Hello there,
I just purchased my second trailer, a 2021 Wildwood FSX 178BHSKX. I'm getting familiar with all the features as my last trailer was a 2010. I have a small switch next to the fridge that was apparently electric water heat but the until has a gas heater with auto start operated from the main panel when you come in the door. Any idea what this other switch is? I thought maybe fresh and waste heaters for cold weather since the underbelly is enclosed but I'm not sure. Any insight appreciated, thanks in advance!

I believe it's for the electric side of the heater, to turn that on. When off and gas is on it should run off-gas. I didn't have that in ours, and I also upgraded to tankless after I picked my trailer up.
