First of all, only the seeTemp wall controls are compatible with the HVAC Controller from Lutron. You mentioned the TouchPro thermostats, and these are NOT compatible with the HVAC Controller. The TouchPros wire up just like a regular old thermostat, and the wireless, ClearConnect part of it is only for temperature set point, fan on/off and feedback, not for connecting to the furnace or HVAC equipment. If you want to have wireless thermostats like the seeTemp, you will also need wireless temp sensors, and as you suggest you would need one HVAC controller for each zone (the HVAC controller wiring looks just like a regular signal zone thermostat).
Hope this helps.
