ST web displays tstat temp range of -460 to 10000F

So I have a ST v2 hub. Today I added a Radiothermostat CT32 thermostat (has Z-Wave module). I can interact with it just fine using the ST app on my iPhone. BUT if I use ST web, the GUI for the tstat displays a heating temp range of -460 to 10,000 degrees. And the slider for the temp setting is useless, as it has to span over 10,000 degrees :). Is there some tweak to the underlying device driver to define a more realistic temp range?

BTW it lists as “Z-Wave Battery Thermostat” both in the ST app as well as the web GUI…

TIA,
Mike
