hello
My first thought is did they prewire a wall thermastat for a second a/c unit if you have a ceiling vent in the bedroom , the wires are there just in case
if you do not have a ceiling vent, they may have framed in a section in the roof structure for a vent/a/c that they can open up and install a second a/c unit
the heat option on the second thermastat may be the heater option on some roof a/c units
just a shot in the dark
Happy Camping
