A pretty long article comes with the picture. The device resolves as Programmable Communicating Thermostat. Just like with ENV-VST-C, California Title 24 is mentioned.
They call the interface simple, but I think it recembles the DZ1 interface (scroll down a bit to find it, it has an unmistakably mainframe feel to it).
Whereas other manufacturers loudly proclaim "money saving features" with pretty vague claims of "up to" "if used correctly", I have a gut feeling that this device does indeed have an emphasis on actual energy conservation.
