Indoor Centralized Controller

Centralized Control

The centralized controller is a multifunctional device that can control up to 64 indoor units within
a maximum connection length of 1,200m. User can group control or individual control and the set temperature of each unit can also different..

Three Lock Modes

A centralized controller provides a superior way to manage the indoor units. Users are able to make their own choice from locking the wireless controller, locking the running mode or locking the centralized controller’s keyboard as they wish.

Wiring Example

The device connects to the master outdoor units of Mitsui’s newly designed products to simplify and centralize the wiring configuration.

The 2 connecting methods are as follow:

*1. If it connects to XYE ports of master ODU, ODU must be set to auto addressing mode.
*2. Some products only can be connected with MD-CCM09 from indoor side XYE ports.

Application Example

Just make sure the address is not repeated and the units can be from different systems, up to 64 indoor units, greatly reducing system limitation.

*1. For 2-pipe system, the running mode should be in the same mode;
*2. For 3-pipe system, the running mode can be set at will.
