Installation assemblies prepared on the site No.
1.2 Installation instructions Installation instructions 1) Connect 220VAC power to the L、N terminals of the centralized controller directly. 2) Do not lay the signal wire and the power wire of the centralized controller in the same power wire pipe, there should be 300~500mm distance between two pipes. 3) The signal wire of centralized controller should not exceed 1200m. 4) No intermediate joint is allowed for the shielded cable. If joints are inevitable, crimp it with the terminal block.

1.4 System wiring instruction Network air conditioner wiring diagram (two types for indoor unit: one is the main control board with an external network interface module; the other is the network interface module is built in the main control board).
Note The RS485-to-RS232 module and the wires in the wiring diagram are used when the network system needs to connect with the computer only. One computer can connect with 16 centralized controllers at most, Namely the maximum of indoor units is 16X64=1024 ,that a network system can connect. The centralized controllers can be distinguished by address code,which setting range is 0 to 15. No duplicate addresses is allowed in a same network. 1.

OPERATION PART Installation & Owner‘s Manual 8
2.1 Function instructions 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.
2.2 Operation conditions 1. Power and voltage range: Input voltage: single phase 198V~242V; AC input power frequency: 50Hz/60Hz; 2. Operating environment temperature: -15℃ ~+43℃; 3. Operating environment humidity: RH40%~RH90%. 2.3 Key words 2.3.1 State indication 1. LED for state indication 1) Normal state ① On The LED will be on when any one of the following occur: a) In the centralized controller network, one or more air conditioners are under operating state.
2.3.3 Emergency stop and forced on When the emergent stop switch of the centralized controller is connected,all the air conditioners in the centralized controller network will be shut down compulsorily,and the LED flashes as 0.5Hz.The centralized controller and computer and all functional modules are disabled from startup and shutdown until the emergent stop switch is break.
3. Mode locking 1) Effect Under mode locking state, through centralized controller to operate the air conditioner, only can choose the mode which has not conflict with locking mode. 2) Operation Can set the heating mode locking or cooling mode locking. Under mode locking state, if set the new mode locking, it must be unlocking first, then can operate the new mode locking. ① Can lock or unlock through the computer. ② Can operate by centralized controller.
2. Use “ ” key to ON and OFF the unit Only can operate all the air conditioners in the centralized controller network, not for single air conditioner. “ ” key long press: press this key for over 2 seconds then loose. “ ” key short press: press this key and then loose within 2 seconds.
14 Installation & Owner‘s Manual the centralized controller press the “Reset”key five seconds to reset TIME OFF SET In the setting page, shift to the timing startup/shutdown setting page. RESET OK TIME ON FAN LOCK SWING DEC INC 1、In the setting page, set the temperature，increase or decrease the time of timing on/off. 2、In the query page ,scroll page of the parameters being queried.
2.4.1 Key operaion instruction 1. Query key “ ” Any time when you press the key, the selected operation mode is to query the operation status of the air conditioner. By default, the first in-service air conditioner will be queried. 2. Set key “ ” In other display mode,press the key “ ” to enter the setting mode. By default, it is single setting, and the first in-service air conditioner is displayed.
9. Rightward key “ ” In the query mode, when the key is pressed, the next in-service air conditioner is selected,and its operation status data will be displayed.If it is currently on the last air conditioner, the first one is selected and its data displays, when the key is pressed. If this key is hold down long, the address will increase one by one. In the setting mode, if it is in the single operation mode, when the key is pressed, the next in-service air conditioner will be selected.
13. Reduce key “ ” 1) Query mode Press this “ ” key, display the data of the previous page. If it is now in the first page, press the key “ ” again and the last page will be displayed. 2) Setting operation mode ① Temperature adjusting method Press this key “ ”, the setting temperature will decrease one degree. If you hold down the key “ ”, the setting temperature will decrease one by one. When reached the lowest allowed set temperature, it can not decrease.

2.4.2 LCD instruction 1. General display data 1） General display data is displayed in all display pages. ①The icon displayes when the centralized controller communicates with the computer or gateway normally, otherwise, it does’t display. ②The icon displayes when the centralized controller communicates with the functional module normally,otherwise, it does’t display.
a. The array of the liquid crystal display is composed of 4X16 grids, and each grid is composed of two blocks of different sizes (as shown in the above figure). The status indication table is as follows： Status Object Constantly on Big black block Small black block In-service Power on Slow blink Fast blink Not bright Out of service Selected Fault of indoor/ outdoor unit Power off b.
2) Description of the query page Fig 2.6 The example diagram of the query page ①The LCD display shows the query page, and the air conditioner with the address of 01 is being queried. ②Mode of the air conditioner with the address 01 is: Cooling, strong air, swing on, indoor temperature 22°C,set temperature 20°C, cooling mode “lock”. ③In the array, only the big and small black dots at (00+,00) and (00+,01) are luminous .
4) Fault page display description Fig 2.8 The example diagram of fault page ①Query the air conditioner with the address of 08 in the query page. ②The air conditioner with the address of 08 is faulty, and fault code is 08. The big black dot below (00+,08) blinks. ③In the array,only the big and small black dots at (00+,00) and (16+,15) illuminate. It indicates the in-service status of the air conditioner power on, with the addresses 00 and 31.
