INSTALLING ACP BACnet

Setting the indoor unit address

By considering the entire installation configuration connecting to one ACP BACnet, 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.
Notes
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 second digit as the
number or the indoor unit, for easy composition and
classification of the system.
Here is an example of configuring ACP BACnet and the device.
