Abstract:
1. A method of controlling a gas water heater having a warning function, the gas water heater including a main body and a gas detecting unit, the gas detecting unit including a processor and a sensor, the main body including a gas water heater controller and the gas water heater being disposed in a facility, the method comprising: disposing the gas detecting unit at an indoor monitoring point separate from the main body; the processor outputting impulse signals through on-and-off pipes to control the sensor; the processor detecting whether the sensor is operating properly; the gas detecting unit sensing a gas concentration; the gas detecting unit converting the sensed gas concentration into a gas concentration value; the gas detecting module unit transmitting to the controller a signal based on the gas concentration value; comparing the gas concentration value with a threshold; and the controller initiating a warning after the gas concentration value traverses the threshold.
