Where Does the Bare Copper Wire Go on the Furrion Chill HE RV Air Conditioner System

Question:

Im installing my Furrion A/C unit. Model #FACR 15 HESA-PS. My order number was #114776959. Coming out of the control box are 4 wires. White NUETRAL, Black LINE, and Green GROUND. The fourth wire is a bare copper wire in a plastic tube. At first, I thought it was a freeze sensor for the evaporator, but it doesnt reach the evaporator. What is this wire? Thanks,

The bare copper wire with clear tube on the control box of the distribution for the Furrion Chill HE RV Air Conditioner System part # FR92PR is an air temp sensor. It needs to be pointed straight up toward the overhead unit. It does not correct directly to any other wires or devices.
