Description
The Lennox 71W49 Manual Reset Rollout Limit Switch is a thermally secure control component installed in HVAC systems to monitor high-temperature conditions and turn off. It has a temperature-sensitive component that closes its electrical contacts when the temperature in the area reaches the 210°F limit to prevent thermal conditions by cutting off fuel or electrical power. The switch is fitted in the secure control circuit in areas where excessive heat can be generated. It allows for controlling shutdown and securing the system by manually resetting in an overheat condition.
