Abstract

PURPOSE:To make it possible to temporarily operate an indoor machine by providing the tile control unit with a mechanism for detecting a transmission error occurring between a remote controller and an indoor unit and making operable the air conditioner by operational data of an ROM of an indoor machine microcomputer when the transmission error occurs. CONSTITUTION:A control circuit 5 placed on the indoor machine, conducts a serial transmission of data transmitted from a microcomputer 2 of a remote controller 1 to a transmission buffer 6 via a transmission line 4 from a microcomputer 2, and receives the data at a serial transmission port 8 of a microcomputer 7 thereby to store the data in an ROM 12 through an accumulator 9. At this time, the control portion carriers out a parity check and the like to detect an error. When an error has been detected, the mode of operation of an emergency operation switch 13 is read out from an input-output port 10. At the 'ON' time (emergency operation), whether the mode of operation of a space cooling and heating operation changeover switch 14 is read out from the input-output port 10. By use of this data, an emergency operation is carried out based on operation data within the ROM 12 when the transmission of data returns back to the normal state, the air conditioners is automatically restored to the normal operation.

Next, I will explain the first assistant. The open side circuit 5 has a YC on the indoor unit, and the remote control information (start/stop, air volume, etc.) sent from the microcomputer 2 of the remote control 1 is serially transmitted from the transmission buffer 3 to the transmission buffer 6 vc through the transmission line 4, and then sent to the microcomputer 7. It is received by the serial transmission port 8 and stored in the RAM 12 through the accumulator 9. At this time, errors such as baritichi and book are detected. If no error is detected, operation is performed using the contents of RAM+2. In addition, if an error is detected, read the emergency operation switch 13 from the input/output boat 10, and when ON (emergency operation), read the cooling/heating changeover switch 14 from the input/output boat 10 to determine whether it is cooling operation or heating operation. Using the information, RO8 is operated according to the operation information in 12.
