Nice clean schematic.
You will probably need more then a simple proportional control.
PID = Proportional, Integral, Differential control of a heater with Unknown Mass Lag.
How do you expect the heater to approach your desired set point.
A) Slowly with no overshoot..
B) Fast with diminished oscillation..
C) Self adjusting for optimum response.
.
BTW we see no code to speak of..
