I am looking to know whether Trane ComfortLink II XL850 Wi-Fi Thermostat (https://shop.rfwel.com/trane-comfort...fi-thermostat/) can work as a replacement for my White Rogers units. Currently, they are being used with two 2-stage Goodman furnaces GMV9/GCV9. I also wish to monitor the external temperature and feed that information to both thermostats wirelessly.
Based on the system I have described, can the XL850 work for me? What is the best way to go about this?
