Part 4/7:
To ensure precise temperature maintenance, the system utilizes proportional-integral-derivative (PID) control algorithms. Currently, there are three PID algorithms in play within the setup. Each algorithm monitors different aspects, primarily concerning the active insulation, and responds to real-time data to adjust the heater’s output as needed.
The various indicators — amber for active insulation, blue for the tube's heater strength, and red for the fan operations — provide visual cues regarding the system's functionality. These lights indicate how the system balances heating and cooling, striving to maintain temperature within a tolerance of plus or minus one-thousandth of a degree Celsius.
