Upon inspection, it was determined that the system required a new control board to function properly. The previous control board was unable to adjust the temperature settings, causing the system to remain idle and unresponsive. I replaced the faulty control board with a new one, ensuring compatibility with the existing system. After installation, I tested the system to confirm that the temperature settings could be adjusted and that the system was operational. The system is now fully functional, and the temperature can be changed as needed.
