Vera and Radio Thermostat CT50?

I just installed a new Radio Thermostat CT50 with the zwave plus module, and added it to my vera. This worked, except for one oddity - it created TWO thermostat devices (both of which seem to update and control) as well as a “temperature sensor” device (which does not show any data) and a “Humidity Sensor” device (which also doesn’t show any data, for obvious reasons). Why might these extra devices have been created? Is there a way to get rid of them? I can, of course, just ignore them, but I would prefer to not have to, if possible.
