Engineering: Part count is too high, redo this with max one screen and three buttons. You know 7 screens costs almost 7 times as much as one screen right?

Industrial Design: [Drops a brick with a photo of Dieter Rams' original Braun radio taped to it onto your head from 3 storeys up]

Edit: non-joke feedback- this is great from a techie perspective but it's too much actual hardware complexity and visual presence for a task that will be done maybe twice per season. You have added about 50% to the cost of goods sold to do this - is it worth it? Will people buy it? Yes I understand this isn't a totally serious device proposal, but I would love people to try to understand why things end up looking like they do!

Who says those buttons have to be physical? With the near-ubiquity of touchscreen interfaces, that should be trivial to build for dirt cheap.

Where are you getting touchscreens large enough to comfortably fit that entire interface for dirt cheap?

I mean that's what my current thermostat actually is. Once you've gone back to touchscreen, as a designer you'll realize that people can't see the tiny text, and you have to display contextually relevant information in large type, and you're back to a touchscreen with menus.
