I figured out how to do this using the older Card Access driver (from 2009) for the WCS10A-2-ZP and not the newer one labeled Control4 (from 2015).
Then, to display the temperature, I used this driver (also from Card Access)
That Thermostat Display driver allows you to select a Source Device under the properties and voila, the temp shows up. However, if you use the Control4 driver for the WCS10A-2-ZP, then the source device won't show up as a selectable device.
