Communication wiring between the indoor unit and wired controller
The wired controller and the indoor unit can be connected in different manners, depending on the forms of communication.
1. For a bidirectional communication mode:
Use 1 wired controller to control 1 indoor unit or 2 wired controllers (one master and one slave controller) to control 1 indoor unit.(see
Fig.4-4)
Use 1 wired controller to control multiple indoor units or 2 wired controllers (one master and one slave controller) to control multiple
indoor units. The maximum number of connections is 16.(see Fig.4-5)
2. For single direction communication mode:
Use 1 wired controller to control 1 indoor unit
The X1/X2, D1/D2 ports on the sides of the main control board and single direction communication port are for different types of wired
controllers.
For the specic connection method, refer to the instructions in the corresponding wired controller manual to carry out the wiring and
connections.
Handling the Electrical Wiring Connection Points
Once the wiring and connections are done, use tie straps to secure the wiring properly so that the connection joint cannot be pulled apart
by external force. The connection wiring must be straight out so that the cover of the electrical box is level and can be closed tightly.
Use professional insulation and sealing materials to seal and protect the perforated wires. Poor sealing may lead to condensation, and
entry of small animals and insects that may cause short circuits in parts of the electrical system, causing the system to fail.

Operatio Manual
There are two types of precautions as described below:
Warning: Failure to comply may lead to serious injury.
Caution: Failure to comply may lead to injury or damage of the
unit. Depending on the situation, this may also lead to serious injury.
Once the installation is completed, please keep the manual properly
for future reference. When this air conditioner is handed over to oth-
er users, make sure that the manual is included with the handover.
Warning
Do not use this unit in locations where ammable gas may exist.
If ammable gas comes into contact with the unit, a re may
occur, which could result in serious injury.
If this unit exhibits any abnormal behavior (such as emitting
smoke) there is a danger of serious injury. Disconnect the power
supply and contact your supplier or service engineer immediate-
ly.
The refrigerant in this unit is safe and should not leak if the
system is designed and installed properly. However, if a large
amount of refrigerant leaks into a room, the oxygen concentra-
tion will decrease rapidly, which can cause serious injury. The
refrigerant used in this unit is heavier than air, so the danger is
greater in basements or other underground spaces. In the event
of a refrigerant leak, turn off any devices that produce a naked
ame and any heating devices, ventilate the room, and contact
your supplier or service engineer immediately.
Toxic fumes may be produced if the refrigerant in this unit
comes into contact with naked ames (such as from a heater,
gas stove/burners, or electric appliances).
