Mystery switch/Unknown switch

[Smurf]

I have a mystery switch that no one seems to know what it is for. Hard to describe but I own a cyclone 2019 4007 model trailer. Under the control panel there is a red switch by itself. Please see picture for some insight. I just want to know what it's used for cannot find anything about it and where I bought the trailer they have no clue either they said it's for the garage ac which is false because I can run the ac there without switching the switch on. Thanks for any help.

Probably for the artic package, heating pads for the tanks.

If you use, make sure you have water in the tanks.

On our Cyclone with the Yeti package, there are two switches for it. The red switch is for the waterline heat tape to keep your fresh waterline from freezing. There should be another switch labelled "Yeti" and that's for the holding tank heater pads. As mentioned before, don't ever turn that switch on unless you have some water in the holding tanks. Heartland has a couple of good videos on Youtube that explain the function of these switches. https://www.youtube.com/c/HeartlandRVs1

Thank you finally I found my answer. It is in fact the main waterline heater.
