PURPOSE:To obtain a preferable warm-air temperature, by a method wherein the amount of combustion is changed automatically in synchronizing with the amount of ventilation usually, however, only the amount of ventilation of warm-air or the amount of combustion is increased or decreased manually by a predetermined amount if necessary when the amount of the combustion is smaller than a predetermined value. CONSTITUTION:A controller 10 is constituted of the room temperature detecting means 11 of a room temperature detector 7, an amount of combustion control means 12, changing the amount of combustion in accordance with the detected room temperature and a preset set temperature, a fan airflow rate control means 13, outputting an information on the rotating number of a fan 8, which is preset in corresponding to the amount of combustion one to one, a switch treating means 14, reading the operating state of switches arranged on a panel 9, a correction judging means 15, judging a correcting operation command by a manual switch switch only when the amount of combustion is smaller than a predetermined value as effective, a fan airflow rate correcting means 15', adding the amount of correction command by the switch treating means 14, and a fan driving means 13', inputting the information on the operating number of rotation of the fan 8 and regulating the fan 8 to a set number of rotation. |
