Description
The Reznor RZ196949 Manual Reset Limit Switch/Thermostat Red interrupts electrical operation when internal temperatures exceed the 225F safety threshold during heating cycles. Its temperature-sensitive switching mechanism opens the control circuit under excessive heat conditions and requires manual reset after the temperature returns to an acceptable range in HVAC systems. This limit switch is mounted near heat exchanger or burner sections where temperature protection is necessary for safe operation. Its manual reset operation assists with overheating protection, reduces thermal stress on components, and supports controlled system recovery after high-temperature shutdown conditions.
