The central control adaptor is a dedicated device that can be
directly connected with the indoor unit for converting
communication protocols and connects the indoor unit to
central control network.
Precautions for arrangement:

Central Control Adaptor
Installation Instructions
Model: B544(E)
1. The design and installation of the central control adaptor should
be performed under the unified planning for central control
system. The installation location of the central adaptor, electrical
distribution and wiring, address assignment, connection with
Modbus monitor and indoor unit should be planned in advance.
2. Cables for central control and distribution lines shall not be too
close to each other or routed in the same conduit. RS-485 bus
should be arranged as far away from interference sources as
possible, especially high voltage interference sources, such as
transformer and frequency converter. For other relevant
precautions, see the requirements for wiring of building
automation system.
3. The equipment on either end of the group control bus must be
provided with terminal-matched resistor.
4. The central control line must be configured as a daisy-chain bus
topology. If a star-type or tree topology is required, it is
recommended to use RS-485 hub and RS-485 repeater.
5. The central control adaptor should be installed close to the
electronic control adaptor of the indoor unit.
6. The baud rate of the adaptor must be set the same with
Modbus/ BACnet monitor.
between the indoor unit and the central control adaptor is 40m,
and the maximum allowable length of RS485 control cable is
1000m.
Please install it in the ceiling and close to the electrical control
of indoor unit.adaptor

3. Setting of DIP switches
Please set DIP switches according to the actual conditions.
Settings after power on will not take effect.
Methods for setting DIP switches:
Before setting, slide down the cover on the central control
adaptor. After setting, reinstall the cover to adaptor. As shown in
Fig.3.

Notes:
1. The above requirement for wiring is the minimum;
2. The central control communication line should be provided by users;
3. Correct polarity of the cable should be ensured during connection;
4. The cable should be reliably secured after connection is completed.
