How would I make a HVAC simulator to see what a thermostat would do if the indoor temp was 425°F (frozen pizza cooking temps) (reddthat.com)

I bought a nest gen 2 thermostat to play with a open source project that revives old nest thermostats (https://nolongerevil.com/). Since I don't want to install it into the home, because it will be a toy. I was thinking of building a test rig using a arduino or esp32 to simulate a HVAC and indoor temperature. I'm IT guy, not a HVAC guy, I think this would be a good learning project. Any suggestions?

It contains lots of plastic, that will melt. Also, electronics are designed to work up to 80°C or so, then there is some safety margin, and then they will also just cease to function correctly.
