However, in the case of I/O module, address 00 should not be set because address 00 is used as a Broadcast in MODBUS communication.

NOTE
Assigning an indoor and outdoor unit number

If the outdoor unit product is Multi V, it is recommended to assign the address by setting the first digit of the address as the number of the outdoor unit and classifying the second digit as the number of the indoor unit, for easy composition and classification of the system.

Here is an example of configuring ACP 5 and the device.

NOTE
How to set the central control address of the indoor unit
The central control address setting method may be different for each indoor unit product or remote control type, so set the address by referring to the manual of the indoor unit
product or wired remote controller.
