1. Centralized controller is used for controlling and data querying of air conditioners in the network.
Each centralized controller can be connected to maximum 64 indoor units, through 485
communication can to form an air conditioner LAN and realize the centralized controlling
network in the air conditioner.
2. Centralized controller can connect with computer or gateway, to realize the LAN connection
between computer and all the air conditioners , then can use computer to remote control
(the computer software must support it). Each local computer or gateway maximally connect
16 centralized controllers.
3. Between centralized controller and air conditioner, computer and centralized controller are
applied to the master-slave responding communication method. In the LAN of centralized
controller and air conditioner, centralized controller will be the master unit, and the air
conditioner will be the slave unit. In the LAN of computer and centralized controller, the
computer or gateway will be the master unit, and the centralized controller will be the slave unit.

4. For the new series product, we can connect the indoor CCM controller via XYE port of master
outdoor unit of every refrigerant system. Notice that in this case, the outdoor unit must be set
to automatic serching address mode. And it will be effective after about 6 minutes.
5. To connect indoor CCM controller via XYE port of indoor unit, this wiring method is suitable for
all type of indoor units, not just for new indoor units.
6. When new indoor units and old indoor units mix connect to one refrigerant system, we can just
connect the indoor CCM controller via XYE port of indoor units. If we connect the indoor CCM
controller via XYE port of master outdoor unit, the CCM controller can not control old indoor
units.
7. If one system that connect to indoor CCM controller include 10 HP or above duct indoor unit,
we recommend you set the address of every indoor unit manually.
