Which control is responsible for shutting off the burner due to excessive temperature or pressure?

The High Limit Control is designed specifically to monitor the temperature of the heating appliance and is crucial for safety during operation. When the temperature reaches a set point that exceeds safe levels, this control will activate and shut off the burner. This automatic response prevents overheating, which could lead to equipment damage or hazardous situations, offering both operational safety and equipment protection.

In heating systems, maintaining optimal temperatures is fundamental for efficiency and safety, and the High Limit Control serves as a critical fail-safe mechanism to prevent dangerous conditions. Hence, it plays an invaluable role in ensuring that the heating system operates safely within designated parameters.
