The LP furnace WILL run when in HP mode if the set temp is more than 5 degrees from the temp of the RV. Your RV is at 60 degrees, you put in HP mode at 66 or higher. BOTH the HP and furnace will run. In FURNACE only mode, the HP will never run. You are stating that when you set at either HP or furnace, either will never shut OFF when the set temp is reached and will heat the RV until you sweat? But it functions in COOL mode OK? Do you have the HP mode fan in the AUTO position when running in HP mode? If not, then when it reaches temp the HP heat side will shut down but the fan will continue to run. Doug
