When you set the temperature control on an oven or anything else, that is not giving you the actual temperature that the food, eg meat, is heating to.
You have to use one of those stick-in food thermometers to find that out.
So you might stick a roast in the oven at 200 but when you look at the thermometer it will tell you that when it reaches say 80 in the centre it is ready for underdone or some higher figure for well done etc.
I think I'm right in saying the temp control just gives you the environment temp not the food temp.
Yes, that's my understanding.
A proportional control is significantly different to the 'normal' cheap controller used in the electric frying pans.
A proportional controller applies 100% power when it is heating, say heating up to 120 degrees.
Once the temp gets close to 120 degrees the power supplied drops back to 80%, then 50%.
So the temp reaches 120 degrees and does not go too much higher.
Once the temp drops the power applied rises a bit.
So the temp in the pan will vary from 115 to 125 degrees when it is set to 120.
If a pan had that, it'ld be the rolls Royce for cooking.
