The central controller is an optional control component for users to monitor and control
operation of air conditioner in a centralized way.
The central controller can be used for unified management of the air conditioners in the
group/zone, querying and displaying on LCD the state of the main functions of the air
conditioner, weekly timer/simple timer setting or querying by keypad entry or setting of
main functions of air conditioner.
Communicate with the indoor unit in the central control network
It can communicate with the wired controller/indoor unit through RS485 communication
bus (shielded twisted pairs with polarity (A+ B-)). The indoor unit can be controlled centrally
or locally by using the wired controller, or centrally controlled by using converter (to be
purchased by users separately).

(1) Cables for central control and distribution lines shall not be too close to each other or
routed in the same conduit. RS485 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;
(2) The total length of the central control bus should not be more than 1000m (at the baud rate
of 9600 bps);
(3) The appliance on either end of the central control bus must be provided with terminal-
matched resistor. See the dip switch setting instructions for central controller/wired
controller/central box;
(4) It is recommended that single-point grounding of the shielded cable shall be arranged in
the middle of communication bus and close to the central controller;
(5) Central control line topology should be daisy-chain bus arrangement. If star topology or
tree topology is required, it is recommended that 485 concentrators and 485 repeaters be
used.
4. The wiring and installation of the central control network should be performed along with the
installation and commissioning of air conditioner. Test run should be performed before
installation.
5.The primary and secondary controllers can be set to operate at the same time in one central
control system with at least one controller as the primary central controller.
Check and confirm that in addition to the wired controller, the following accessories are
included in the packaging box:
