2. SUMMARIZE OF OUTDOOR CCM

Warning

Delegate installation

Please entrust the distributor or professionals to install the unit. The installers must have the relevant know-how. Improper installation performed by the user without

permission may cause re, electric, shock, personal

injury or water leakage.

Usage

Warning

Forbid

Do not spray ammable aerosol to the wire controller directly. Otherwise, re may occur.

Forbid

Do not operate with wet hands or let water enter the wire controller. Otherwise, electric shock may occur.

The functions only can be realized when the system is in normal operation.

1. Central Control Monitor can realize the central control and data query to outdoor units. One outdoor CCM can

connect max 8 refrigerant system by

NIM, so each outdoor CCM can connect

max 8 systems are multiplied by max

4 sets outdoor units per system equals

max 32 outdoor units. And it adopts

wire-connecting method communication

to realize central control to the outdoor units in the same network. .

2. CCM can communicate with PC

through RS485/RS232 converter. One PC can connect max. 16 outdoor

CCM and 16 indoor CCM. And PC can realize central control to outdoor units, central control to indoor units, central control to indoor units and outdoor units, management, status query and so on.

3. The CCM and outdoor units, PC and

CCM adopt main-auxiliary responsion

communication. In the network of CCM

and outdoor units, CCM is the main unit

and outdoor units are the auxiliary units.

3. BASIC REQUIREMENTS

1. Applicable Power Voltage Range:

Input Voltage 220~240VAC.

2. AC Input Power Frequency:

50Hz/60Hz.

3. Working Ambient Temp.:

-15°C(-5°F)~ +43°C(+109°F).

4. Working Ambient Humidity: RH40%~

RH90%.
