Re: This should be considered safety critical software

Considering that old and infirm can literally die of cold (let's face it just about anyone can die in a Canadian winter), something like a thermostat house should really be treated like, and designed as well as, medical equipment.

Fixed that for you. If you're in a situation where people can die of hypothermia in their own homes, you need to look at the house as a complete system. Good insulation is probably more important, and ensure there are backup independent heating sources - a bulletproof thermostat is no good if the boiler goes kaput.
