Trane XL850 or XL950 with Nexia Bridge

Has anyone been able to get either of these thermostats paired with Vera? They both can act as a z-wave controller but it’s not clear if you can pair it to another controller as a z-wave thermostat.

Are you certain that these thermostats offer Z-Wave communications? The XL624 does, and I have one installed and manageable through Vera, but the two models that you identified seem not to be Z-Wave devices.
