Next, the operation of the system configured as described above will be described with reference to the block diagram of FIG. 3, the flowchart of FIG.
Will be described with reference to a diagram showing a communication sequence between the IFU, the central unit and the terminal. When adjusting the set temperature of the air conditioner 1a from the central unit 4, the central unit 4 sends an initial identification signal to the IFU 3a to instruct the type of the external control terminal of the connected device and the terminal model confirmation. IFU
In response to this, 3a transmits an identification signal based on the serial transmission sentence pulse signal as shown in FIG. 4b to the terminal device 1a from the transmitting means.

For example, it is 123,2 ms.

Since the terminal 1a of the air conditioner receives this serial signal and itself complies with the JEM-S standard which has the ability to decode and process the serial signal, it understands the information content of this serial signal and returns the response signal. As a response, an ACK (acknowledge) based on the JEM-S standard and a response signal by a predetermined serial transmission sentence pulse signal are transmitted within a fixed time. If a normal serial signal cannot be received due to a line trouble, etc., NAK (negative)

When the IFU 3a receives the response signal from the terminal device 1a by the reception means, the terminal device 1a determines whether the response signal by the predetermined serial transmission sentence pulse signal has been received by the determination means by the JEM-S. It is determined that the device is based on the standard, and the information is transmitted to the central device 4. When the central device 4 confirms that the terminal device 1a is JEM-S based on this information, the terminal device 1a is capable of adjusting the room temperature setting by the serial signal, and therefore instructs the change of the set temperature. In response to this, the IFU 3a transmits an operation control signal based on the JEM-S standard to the terminal device 1a, and the terminal device 1a receives this and changes the set temperature.

Although the terminal device 1c receives this identification signal, it itself complies with the JEM-A standard and the pulse width of this identification signal is less than 200 ms. It is determined that the signal is not a signal, error processing is performed, a non-responsive state is maintained without changing the output level value of the operation monitor signal, or code information indicating that the terminal device is not a NAK or JEM-S standard is returned after a predetermined time. According to the JEM-A standard, the response start time of the operation monitor signal is determined and after the timing of the response signal returned by the terminal device of the JEM-S standard, the determination means of the IFU 3c is the terminal device 1c. Is JEM-S
It is determined that the terminal is not based on the JEM-A standard, the information is transmitted to the central device 4, and the central device 4 confirms that the device is JEM-A. Then, the terminal 1c adjusts the indoor temperature setting. Since it is impossible, JEM-A

The contents of the control are ON / O in JEM-A.
Since only FF control is performed, for example, the instruction from the central unit is ON.
Or, if it is related to OFF, the operation control signal for ON / OFF switching according to the JEM-A standard is sent to the terminal device 1c.
May be transmitted to the central apparatus, or if it is related to the setting of the room temperature, a display indicating that the instruction cannot be accepted may be output to the central device. Further, if, for example, in response to a demand control request from the central unit 4, an instruction to increase the indoor set temperature during cooling or an instruction to decrease the indoor set temperature during heating, the OF
It is also possible to temporarily stop the air conditioner by transmitting the F signal.

Further, according to an experiment conducted by the circuit of FIG. 2 in the present invention, at the initial stage of the whole system startup, for example, the IFU 3c uses the JEM-A standard terminal device 1c based on the initial identification signal from the central unit 4. On the other hand, when the above-mentioned identification signal is about to be transmitted, if a driving instruction is given by another driving operation device such as a local remote controller of the terminal device 1a, a driving monitor signal is output from the terminal device 1c.

Once the operation is canceled, the operation monitor signal of the terminal device is set to Lo.
After opening the signal line, the identification signal is transmitted to perform the above-described discrimination and control. This enables reliable control based on the JEM-A standard even in the case of JEM-A terminal equipment.

With the configuration and method as described above, it is possible to perform appropriate control from the common central unit to the terminal devices of the respective standards of JEM-S and JEM-A within the range conforming to the respective standards. . In the above embodiment, the case of the air conditioner is described as an example, but it goes without saying that it can be applied to terminal devices other than the air conditioner, for example, other HA devices such as a water heater, and systems other than the HA system, The same configuration and method can be applied to a system combining them.

Example 2. FIG. 8 is a main circuit configuration in the case where a terminal conforming to the JEM-S standard, such as the terminal 1a of the air conditioner of the above-described first embodiment, is connected as a master unit and another JEM-S standard terminal is connected as a slave unit.

In the circuit configuration inside the terminal device, the circuit configuration other than the jumper wire 1h complies with JEM-S.

Next, the operation will be described. Usually, the terminal is mainly the child device side of the system as in the first embodiment,
In such a case, if the jumper wire is short-circuited, it becomes a normal JEM-S serial HA terminal or a JEM-A HA terminal, and functions as operation control and operation monitor.
Also, for example, if you want to operate the air conditioner as a master unit by connecting a ventilation fan or heat exchange ventilation device as a slave unit to operate in conjunction with the operation of the air conditioner, or want to control the ventilation fan or heat exchange ventilation device from the air conditioner side. In this case, as shown in FIG. 7, circuit connection is established between the terminal devices via an adapter, and the jumper wire 1h of the terminal device 1g is cut off so that the air conditioner 1g serves as the master unit and the terminal devices 1i, 1j such as ventilation fans become slaves.

Signals are connected to the terminals 6g, 6h, 6i of the IFU side terminal section, the terminals 3g, 3h of the 3-wire type pulse meter side terminal section of the IFU 3, and the auxiliary input terminal 3i. With the above configuration, the information of the 3-wire type pulse meter is sent to the central unit (corresponding to the central unit 4 in FIG. 1), and the central unit collectively manages the amount of gas, water, etc. used in each room and the price. It will be possible.
