Abstract

PROBLEM TO BE SOLVED: To provide a microcomputer with flexibility by a method wherein propriety of execution of a comfortability function to change the direction of a wind direction plate according to an indoor temperature is controlled by the parameter value of an external memory device. SOLUTION: From an indoor temperature detecting means 1 and an external memory device, a parameter 2 of a control system is inputted, and when the propriety parameter of execution of comfortability control is practicable, stability of an indoor temperature is decided and an air-conditioner is controlled by a control means 3. First, heating operation is checked and comparison between an indoor temperature and an indoor set temperature Ts is performed. When, during heating operation, it is confirmed that an indoor temperature is stabilized, a wind direction plate is changed into a down state and a horizontal direction at intervals of a position holding period, and an indoor temperature is uniformized. This constitution easily copes with a kind of an air conditioner different in a control system.

The control means of the present invention stores a portion for inputting selection parameters for each control method of the air conditioner from an external storage device, a portion for storing the input parameters, and an output signal from the indoor temperature detecting means. The part to input, the part to store the previous room temperature, the part to compare the data input the output signal from the room temperature detection means with the room set temperature, the previous room temperature and the current room temperature Immediately after the microcomputer is reset, the operating clock is output from the output pin, the parameter storage address is output from the input / output pin, and the parameters of up to 128 bytes are read from the input / output pin. Stored in RAM inside the computer. If the parameter corresponding to whether or not comfort control can be executed is executable, the difference between the previous room temperature and the current room temperature will be smaller than a certain value, and the room temperature will be higher than the indoor set temperature. In this case, it is determined that the temperature of the room is stable, and the position of the wind direction plate is changed in a downward direction and a horizontal direction at a constant time period so that the room temperature is controlled to be uniform. If the parameter is execution prohibition, comfort control is not executed. By this method of selecting the control method by the external storage device, it is possible to obtain the parameters of up to 128 bytes with the output terminal and the input / output terminal of the microcomputer and the space on the control board which is very small. , Controls that could not be selected before can now be selected.
