LG BECON HVAC BACnet PQNFB17C1 Installation & User Manual page 93

It is installed by interfacing 16 room central controller and the ACP BACnet, but some
indoor units are not recognized, or not properly performing the central control commands
• It is the case of incorrect setting of the simple central controller (16 room central controller)
DIP switch.
Set all simple central controllers to Slave mode, and reset the power.
• If the indoor unit to control with simple central controller is in another physical line as in the
following figure, the simple central controller cannot recognize the corresponding indoor unit.
Therefore, the connections need to be modified to have the simple central controller to be in
the same RS-485 communication line with the indoor unit to control.
