Please use TC instead 2) Software issue - if there is some dependency between Temp and Time you should specify it by equation. Then - what outputs do you have? In case you have only 1 output "turn oven on" there must be temperature regulation - in most cases PID regulation would be enough, but you should tune it properly. Summary - please specify your task to get more detailed answers.
