Abstract

PURPOSE:To facilitate the detection of an abnormality occurring in a control circuit of a remote control unit and a faulty place therein by a system wherein the remote control unit is set in the center of the control and data transmitted from indoor and outdoor units with checking items and data indicating the presence or absence of the abnormality included therein are processed and displayed in the remote control unit. CONSTITUTION:In an ordinary operation, a transmission output of a microcomputer 3 is sent to an indoor or outdoor unit through a transmission circuit 1b. In a remote control unit, a transmission signal sent therefrom is received through a reception circuit 1a and transmitted while the correctness of said signal is checked up. When the signal has any error, for instance, an error counter provided in the microcomputer 3 is incremented and the transmission is recommenced from the beginning. When a value in the error counter reaches a predetermined value, it is determined and memorized that a transmission-reception circuit is abnormal. On the other hand, the error counter is reset when a series of transmission is performed without any error. As to switches and volume units 4-7 for various settings, positions thereof are taken in for storage by the microcomputer 3 so that it can be monitored whether the transmission-reception circuit 1 of the remote control unit operates normally.

In a separate nitrogen conditioner composed of outdoor units, the control method connects each unit with a dedicated signal a or power line, and transmits the control signal of each unit in series by applying or superimposing it on the above line. If an abnormality or failure occurs at the location where the air conditioner is installed, the service procedure becomes complicated, making it difficult to identify the abnormality or failure location, requiring special inspection equipment, or requiring special inspection equipment to be installed in each unit at the site. The service method was often to replace only the control board that was present, and even normal boards were sometimes replaced, resulting in poor service efficiency.

ケ提供することを目的としている。Is this invention a drawback of the conventional ones mentioned above? This was done in order to make the remote control unit the center of control, and to process and display data sent from the indoor unit and outdoor unit, including inspection items and data indicating the presence or absence of abnormalities, on the remote control unit. By adding a self-diagnosis function that checks the remote control unit itself for abnormalities and failures and displays the information as necessary, the self-diagnosis function of the separate air conditioner eliminates the drawbacks of conventional models. The purpose is to provide a diagnostic method.

Is this the transmission signal that was just sent from the remote control unit? The signal is received through the receiving circuit lai, and the signal is checked for errors before being transmitted. For example, if there is an error in the signal, the error counter t provided in the microcomputer 3 is incremented and the transmission is restarted from the beginning. When the value of the error counter reaches a predetermined constant value, it is determined that there is an abnormality, and it is stored that the transmitting/receiving circuit 1 is abnormal. On the other hand, if the series of transmissions is performed without error, the error counter is reset.
