IA few months down the road and I realised I wanted to add some alerts; for over and under temperature. Really designed to give some protection from heater failures,
I also removed the 'off' function, totally unneeded and easy to hit accidentally. Now I just say 'already on' and go straight to the countdown reduce (speedup) function.
Apart from that, and some tweaks to the loop timings, syntax etc. It's unchanged. But I decided to make this a major release since It seems like a good point to do that.
