With this operation, the control unit 14 of the input / output setting device 13 stores the function of the input signal a of the external input / output device 17a and the target indoor unit address, and transmits the same to the external input / output device 17a via the signal line 9. . FIG. 6 shows a transmission format at the time of setting. The control unit 14 of the input / output setting device 13 sets the source address to the address of the input / output setting device 13, the destination address to the address of the external input / output device 17a, the transmission type code to the code indicating the external input / output setting data,
A code indicating the input signal “a” is input / output No., and a code indicating the external start / stop signal is input / output function.
, The address of the indoor unit a is set in the target unit address 2, and the address of the indoor unit b is set in the target unit address 2.

Next, the operation of the indoor unit 6 will be described with reference to FIG. The indoor unit a analyzes the data received from the input / output setting device 13 by the control unit 7, and determines whether the destination address data is data addressed to itself. Input / output setting device 1
Destination address of the data from the external input / output device 17
If the address matches the address a, the control unit 7 stores the data and performs input / output control. If the destination address of the data from the input / output setting device 13 does not match the address of the external input / output device 17a, the data is discarded.

Next, the operation of the outdoor unit 10 will be described with reference to FIG. The outdoor unit 10 analyzes the data received from the input / output setting device 13 by the control unit 11 and determines whether the destination address data is data addressed to itself. Outdoor unit 10
Is the destination address data is the external input / output device 1
7, the data is discarded.

Next, the operation of the external input / output device 17 will be described with reference to FIG. The external input / output device 17 analyzes the data received from the input / output setting device 13 with the control unit 18 and determines whether the destination address data is data addressed to itself. When the address of the external input / output device 17 matches the destination address data, the control unit 18 stores the data and performs input / output control. If the address of the external input / output device 17 does not match the destination address data, this data is discarded.

Next, the case where the alarm status signal of group 2 is set as the output signal of the input / output mechanism 19 of the external input / output device 17 will be described.

First, the operation of the input / output setting device 13 will be described. The external input / output setting mode is selected by the setting unit 16 of the input / output setting device 13, and the control unit 14 displays the external input / output setting mode on the display unit 15. First, set the place to output the alarm status signal. First, the external input / output device 17a
Is displayed, and the external input / output device 17a is selected. Then, the output signal a of the external input / output device 17a is displayed on the display 15 by the setting device 16 and is selected. Then, the function of the output signal a of the external input / output device 17a is displayed on the display 15 by the setting device 16 in accordance with a predetermined code, and the alarm status signal code "32" is set.

Next, the indoor unit 6 which is the target of the alarm status signal is set. Group 2 is one indoor unit c,
First, the address of the indoor unit c is set on the display unit 4 by the setting unit 3.
Display and set. In this example, since there is one device, the setting is completed here, but if there is more than one device, this operation is repeated.
By this operation, the control unit 14 of the input / output setting device 13 stores the function of the output signal a of the external input / output device 17a and the target indoor unit address, and transmits the same to the external input / output device 17a via the signal line 9. . FIG. 6 shows a transmission format at the time of setting. The control unit 14 of the input / output setting device 13 sets the source address to the address of the input / output setting device 13, the destination address to the address of the external input / output device 17a, the transmission type code to the code indicating the external input / output setting data,
The code indicating the output signal a is input / output No., the code indicating the alarm status signal is input / output function, and the target unit address 1
Is set to the address of the indoor unit c and transmitted to the indoor unit 6.

According to the above-described embodiment, since the input / output mechanism of the indoor unit and the outdoor unit can be arbitrarily set to a signal corresponding to a group signal of the plurality of indoor units and the outdoor units, the system can be easily constructed.

[0064]

The external input / output mechanism of the indoor unit and the outdoor unit can be arbitrarily set in function and processed in a group, so that arbitrary signals can be exchanged only with each unit with fixed hardware up to now. However, since group processing can be performed, the degree of freedom in system construction is increased, and the system can be easily handled.
