METHOD FOR CONTROLLING HOT WATER AND HEATING WATER IN BOILER WITH AUTOMATIC FUNCTION

PURPOSE: A heating or hot water control method of a boiler including an automatic driving function is provided to automatically use heating or hot water by automatically setting temperature, which is suitable for the heating or the hot water, according to outdoor temperature and indoor temperature. CONSTITUTION: A blower fan is operated according to select of auto mode in an indoor temperature controller, and a signal, which is sensed in an outdoor temperature sensor installed in an air outlet, is transferred to a calculation processing control unit of a main controller in a boiler main body in order to measure outdoor temperature. The measured outdoor temperature is transferred to the indoor temperature controller, and heating temperature and hot water temperature are automatically set based on the outdoor temperature.
