Setting the indoor unit address
By considering the entire installation configuration connecting to one ACP, set the address to each
indoor unit not to be overlapped. 00~FF in hexadecimal can be set to the indoor unit address.
The next section describes how to set the address to each indoor unit by using the wired or wireless
remote controller according to the given number.
The following example sets the address to the indoor unit.
When the ACP is interconnected with the AC Manager, the ventilator can be together installed and
controlled. The above figure shows the example that sets 30 and 31 to the ventilators as address and
connects to the ACP.
Caution: Connecting the ventilator to the RS485
The ventilator and the air conditioner can not be connected together to the same
RS485 communication cable. When connecting the ventilator to the RS485
communication cable, the cable other than the RS485 communication cable
connecting the air conditioner should be used.
