Year and model of coach,? Somebody with similar coach can tell you where they are located
Little brown oval thing , with a slot in it all the way around
The switch on the wall is just the setting control
There electrical control unit is mounted at or near your 120v circuit breaker box
Typically the rear of the coach bath and bed, is on (1) section of the control ,the rest of the coach on the other section
The temp up in the front by the windshield or slide out, will always be different than the bedroom, even with the exact same settings
The front has a larger Warmer area to cool
setting on 'Auto cool' will give a wider swing/variation than
just setting on high cool
its in the manual, where it describes operation of the different modes
I can explain it to you.
But I Can Not understand it for you !
