2. Installing ACP
Tip: Connection setup when using the simple central controller together with the ACP
The simple central controller can be used with the ACP. Connect the simple central controller to the
ACP as follows:
Note: Checking the LGAP Label
Check the LGAP Label at the right side of the case of the simple central controller. Only the product
with the label can be together connected to the ACP.
The VCC and the GND terminals of the simple central controller should be connected to the wire
from the PI485 or the separate adaptor. For more information, see the manual for the simple central
controller.
1. Connect the BUS-A and the BUS-B ports of the PI485 to the terminals C and D of the simple
central controller by using the RS485 communication cable.
2. Set the rotary switch of the simple central controller to match with the group number of the indoor
unit to be controlled. For example, in order to control the indoor units with the addresses 00~0F,
set the rotary switch to 0.
3. Set the DIP switch No. 1 of the simple central controller to OFF (slave) and No. 2 to ON (LGAP mode).
