@stefano I wonder if this is perhaps a fundamental difference in design between some of the EU and US equipment.

Maybe it's only older equipment in the US that doesn't do this and Honeywell had to build it into the thermostat to cover themselves legally?

@stefano I wish I could find the HN comment by the Honeywell engineer that talks about like 6 different safety features none of the open source DIY thermostats have but I cannot seem to find it anymore. Stuff like

- it needs to lock out instead of continuing to try to start the gas heat so you don't flood the house with gas if the ignition is faulty

- it needs to automatically turn on the heat no matter what if if gets too cold

- it needs a mechanical safety feature to shut itself off if the heat gets stuck on

etc etc
