Title: heater verification - compare with the effective pwm value

To verify heater and sensor we should compare with the effective pwm value.
This avoids floating point comparisations and takes into account that the pwm is only set, if temperature is within the correct range (see line 484). In other cases the calculated pid_value is refused - so i would prefer to not use this variable afterwards for verification.
What do you think?
