The temperature of the heating water passing through a bypass pipe is detected by using a thermistor installed in the bypass pipe by the signal of the ignition sensing step(S1). A signal is transmitted to a set up time elapsed step(S3). If the set up time is not elapsed, a signal is transmitted to the temperature detecting and storing step by deciding the elapse of the set up time. The temperature is continuously detected and stored. If the set up time is elapsed, a signal is transmitted to a step(S4) for comparing temperature fluctuation per unit time. If the rate of temperature fluctuation is over zero, a signal is transmitted to a normal operation step(S5). If the rate of temperature fluctuation is the same as or under zero, a signal is transmitted to a step(S6) for stopping operation and indicating an error. Then, the operation of a boiler is maintained. After stopping the operation of the boiler, the disorder of a float switch and the running out of water in the boiler is displayed on the display window of a room controller.
