Aim for the the program is to control the air pressure in an enclosed tank via a heating element. I'm assuming due to getting an error with the PID status instruction being false, the PID/Auto tune/PWM/heating element won't activate/start. Other than that, pretty lost on why the system isn't functioning. We've checked that all sensors are working.
