I have a different and older model Puma, and there are only three switches near my thermostat/A-C/heater controls outside the bath. They turn on the bathroom light, the light in the shower, and the fan in the vent in the bathroom, if the switch at the fan is turned on. My bedroom light is near there, too. Perhaps yours are similar, if not the same. There may be switches at the lights, too, and if those are turned off, then the wall switches don't do anything.
