What is the typical temperature setting for a high limit control?

The typical temperature setting for a high limit control is 200°F. This setting is crucial for ensuring safe operation in heating systems using oil heat. The high limit control acts as a safety mechanism designed to prevent the temperature of the water or fluid in the heating system from exceeding a specific threshold. If the temperature rises beyond this point, the high limit control will shut down the burner, safeguarding the system against overheating, which can lead to equipment failure or even hazardous conditions.

While other temperatures such as 180°F, 220°F, and 240°F may be found in various systems, 200°F is widely recognized as a standard setting that balances efficient heating performance with safety. This temperature is sufficient for effective heating while providing an adequate buffer to prevent any accidents due to excessively high temperatures. Thus, the choice of 200°F effectively combines effectiveness and safety in oil heating applications.
