What distinguishes the Robertshaw LCC and LCH model high limit thermostats from previous models?

The Robertshaw LCC and LCH model high limit thermostats are distinguished by their fail-safe design, which is a critical feature in safety systems. A fail-safe device is engineered to default to a safe condition in the event of a malfunction or failure. This capability is especially important in commercial food equipment, where maintaining safe operating temperatures is vital to prevent overheating and potential hazards associated with food safety and equipment damage.

The fail-safe characteristic ensures that if these thermostats were to encounter an error, they would trigger a shutdown of the heating element or other critical safety measures, thereby protecting both the equipment and the food being prepared. This reliability enhances the overall safety of the cooking environment, allowing operators to maintain compliance with safety standards.

While other options, such as having digital displays or being programmable, may enhance user experience and operational efficiency, they do not elevate the thermostat's essential purpose related to safety in the manner that the fail-safe feature does. Similarly, size might play a role in installation or aesthetics, but the fundamental distinction lies in the robustness of safety features in the LCC and LCH models.
