Setting the indoor unit address

By considering the entire installation configuration connecting to one ACP 5, set the address to
each indoor unit not to be overlapped. 00~FF in hexadecimal can be set to the indoor unit
address. However, in case of I/O module, address 00 should not be set because address 00 is
used as Broadcast in MODBUS communication.

NOTE
Assigning 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 sec-
ond digit as the number or the indoor unit, for easy compo-
sition and classification of the system.
Here is an example of configuring ACP 5 and the device.

When the ACP 5 is interconnected with the AC Manager 5, the ERV can be installed together and
controlled. The above figure shows the example that sets the addresses of 30 and 31 to the ERV
and connects to the ACP 5.
