shadow cruiser furnace
just bought a new shadow cruiser 195wbs- the salesman showed us how to turn on the furnace, but he had a hard time figuring out how to do it and had to call maint tech to show him . Now we cant seem to figure out how to operate it either. Seems to be an issue with the way we are using thermostat. press buttons till reads heat, set temp to 80, but rooftop a/c unit comes on. we remember something about pressing buttons till read aux. , but cant seem to do it right. And yes propane is on and full. any help would be appreciated, thanks.
