PROBLEM TO BE SOLVED: To enable a desired amount of air to be secured by a method wherein a microcomputer is provided for operating a blower in a high speed mode with a more amount of air than that in a normal mode when an air cleaning operation switch is turned ON and a combustion operating switch is also turned ON. SOLUTION: A microcomputer 8 performs a room temperature control to judge whether a (combustion + air cleaning) mode is set, in other words, whether or not a flag for indicating a (combustion + air cleaning) mode is present after a combustion operating switch 10 and an air cleaning operation switch 9 are turned ON together and then if there is a flag indicating a (combusiton + air cleaning) mode, an amount of combustion based on a difference between a set temperature and a room temperature is determined. The number of rotation of a fan motor based on the determined amount of combustion is determined and a high speed number of rotation having a predetermined number of rotation added to the determined number of rotation is also determined and then a control signal of the fan motor based on the high speed number of rotation is outputted from a blower control section 82. |
