Reznor 100799 Limit Control L150-25F

The Reznor 100799 Limit Control L150-25F monitors temperature conditions and interrupts the electrical circuit when heat levels exceed the specified operating range. The sensing mechanism responds to rising temperatures, disconnecting power before excessive heat affects connected equipment sections. In HVAC systems, it works within heating control arrangements where thermal protection is required during burner operation. After temperatures return to an acceptable level the control restores circuit continuity automatically, allowing equipment operation to continue. Its response provides temperature-based protection while maintaining proper interaction between safety controls and heating assemblies during regular cycles.
