Claim:
1. A method for displaying state parameters of a central air-conditioning system using an integrated controller; the integrated controller comprising a central control microprocessor, an LED display, an inquiry button, and a plurality of state parameter detecting units; and the method comprising: 1) detecting data of a plurality of monitoring points by the plurality of state parameter detecting units, and sending the data to the central control microprocessor; 2) receiving an order from the inquiry button by the central control microprocessor, and actively scanning state parameters of the monitoring points by the central control microprocessor by turns; and 3) transmitting the state parameters from the central control microprocessor to the LED display in accordance with the order input from the inquiry button, and sequentially displaying the state parameters on the LED display in a rolling mode; wherein: the state parameters comprise temperature data of each monitoring point; and rotational speed data of an indoor blower, a compressor, and an outdoor blower are calculated by the central control microprocessor in accordance with the temperature data of each monitoring point, and the rotational speed data and the temperature data of each monitoring point are displayed in sequence on the LED display in the rolling mode.
