HEATING APPARATUS AND CONTROL METHOD THEREOF

摘要

A heating apparatus and a control method thereof are provided to open and close a valve based on a predetermined valve opening temperature difference and a predetermined valve closing temperature difference. A method for controlling a heating apparatus comprises the steps of setting target temperature(St) of heating, setting reference temperature less than the target temperature and representing a determining criterion for a closing time point(CT) of a valve, and setting a temperature measurement interval(L1) for measuring time required for temperature variation. Time(L2) used for temperature variation of the temperature measurement interval is measured. Remaining heating time(L3) between a time point(AT) of the reference temperature and the closing time point is calculated in proportional to the time. After the remaining heating time lapses, the valve is closed at the closing time point.
