I have a Trane TCONT803 with outdoor temperature sensor and currently the sensor is reading 30 degrees to high.

What are some options I have to get this fixed? I thought that when I purchased the system and I was reading through the installation manuals that there was a way to calibrate this.

We're getting near temps where my heat pump should be cutting off and switching to gas furnace, but the ODTS is reading way too high. Isn't there a setting under the advanced menu on the stat?

Thanks for the help!
