GAS LEAKAGE INSPECTION SYSTEM CONTROL METHOD FOR GAS BOILER

摘要

The system control method and apparatus prevents safety accidents resulting from a gas leakage by stopping the operation of the boiler, and simultaneously displaying the gas leakage state if the gas leakage is detected. The system control apparatus comprises a sensor (117) sensing the temperature of the hot water discharged from a first heat exchanger (14) via a temperature detector (114) connected to a thermistor (34"); a temperature comparator comparing the measured temperature with a reference temperature; a next step command part (120) ordering the next function by receiving the signals from a gas alarm (17) and the temperature comparator (19); an extinguishing control part (123).
