After replying I noticed Roger had already beat me to it. That's willful infringement if so and I think the penalties automatically triple. To start.

Hopefully some of those patents will go away thanks to prior art. The prior art may not be in the realm of HVAC, but it's hardly novel to apply the ideas to these products.

But even keeping to HVAC, the rotating control around a central display for instance goes back a few decades in thermostat design.
