Checkpoints during the ACP 5 installation

• The number of PI485 connected to one RS485 communication line
  ACP 5 provides 4 RS-485 ports for indoor unit connection. (CH1 ~ CH4)
  Up to 16 PI485 for outdoor units can be connected to one RS-485 port, and up to 31
  PI485 for SINGLE/ERV can be connected.

• The number of indoor units that can be connected to one ACP 5.
  One ACP 5 can be connected up to 256 indoor units. With ACS I/O interlocking, you can connect 128 indoor units and 16 I/O modules. And with chiller interlocking, you
  can connect 128 indoor units and 10 chiller units. If there are a large number of the indoor unit to be connected, the outdoor unit connection should be divided into appropriate BUS forms from CH1 to CH4.
  When connecting up to 64 indoor units per RS-485 port, optimal performance is achieved.
  The maximum quantity of connected indoor units is different depending on the quantity of connected I/O modules.
  Please refer to the following information related to product connection quantity.

• Devices: Indoor units, ERV, DI/DOs, DOKITs, Heatings, AHUs

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 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.
