After searching for hours with no results, I'm posting this.
I have a 2019 Tiffin Phaeton 40 QKH with Aqua Hot. I noticed that the exterior temperature reading on the Spyder panel seemed too high. To verify, I moved the bay sensor outside and confirmed that it's showing 12-14 deg F too high. Problem is that I can't find where the exterior sensor is to see whether it's a location problem or the sensor itself is a problem. After having to move the interior sensors because of bad install location, I suspect the same is true for the outside sensor and it needs to be isolated from the surrounding objects.
Anyone have any idea where this sensor is?
