What is the purpose of a LWCO?

Explanation:
The main idea is protection: a Low Water Cut-Off keeps the boiler from firing when water is too low. Its purpose is to shut off the fuel supply (or trigger an alarm) if the water level falls below a safe point, preventing overheating, potential boiler damage, or a hazardous condition. It detects low water with sensors, and its action is to interrupt the burner control circuit or fuel valve and alert operators. It isn’t about regulating burner temperature, shutting off the water supply, or just measuring water level—the crucial function is to respond to a low-water condition by stopping fuel or sounding an alarm to keep everything safe.
