PURPOSE:To automatically select the optimum output level according to the room temperature, by the control with a prescribed system based on the transition of detected temperature. CONSTITUTION:When a room temperature T transits to a detected temperature region ''00'' from the detection temperature region in excess of the reference temperature T0-alpha, the output level of a burnner 11 is switched to a maximum output level. When the room temperature T exceeds the reference temperature T0+alpha and transits to the detected temperature region ''11'', the output level of the burnner 11 is switched to the minimum output level. Further, when the room temperature T is not transited to the detected temperature region different, that is, when the room temperature T transists from the detected temperature region ''00'' to ''01'' or form ''11'' to ''10'', the output level of the burnner 11 is kept constant. Further, when the room temperature T exceeds the set temperature T0 and transits to the temperature detection region ''01'', the output level of the burnner 11 is switched toward increase, and conversely, when it exceeds the set temperature T0 and trnsits to the detected temperature region ''10'', the burnner 11 is switched toward decrease in the output level. |
