What is this thermostat?

[Scag386]

In our newly acquired 2008 Crossroads Sunset Trail camper there is a thermostat in the bathroom separate of the one in the living area that controls the furnace and A/C unit... I hear it click as if energizing something when moved past the ambient temperature yet do not feel the floor anywhere in the camper warm... The camper has a sealed under-belly and I have seen info online regarding cold-weather packages although I have no original supporting paperwork to affirm or deny this camper having any factory cold weather package.
What could this unidentified thermostat be tied to and how to use???

A picture would help. Maybe it’s for an automatic roof vent in the bathroom?

Very good possibility that it's for a thermostatic controlled roof fan/vent.

Without seeing it my guess would also be a thermostatically controlled fan.

Thank you everyone! The notes about the fan now make perfect sense.
The fan on the ceiling nearby does have an (Auto) position on the powered crank assembly so I would have to assume that is the case. When weather warms up a bit around here will set and see if it does as makes sense.

Dometic has a version of this fan that can reverse the fan to suck air in or push air out.

Fantastic fan also works that way.
