8-1 Capacity setting

Set the dial switch ENC1 on the main control board by different

usage. After setting, be sure to turn off the total power switch

and then switch on. The setting function can not be carried out if

not to turn off the total power switch and then switch on.

● Function specification:

8-2 Master/Slave DX box setting

In a set of the DX AHU box system, it is need to set master DX

AHU box and slave DX AHU box respectively. Please refer to the

definition of SW6(table.10-5). If only one DX AHU box control one

indoor unit, the DX AHU box is the master DX AHU box. If two or

more DX AHU boxes parallel connection control one indoor unit, the

maximum capacity DX AHU box should be the master box, second

largest capacity box should be the slave 1, third largest capacity

box should be the slave 2 and so on. The sum of DX AHU box

should less than or equal to 4.

8-3 The quantity of slave DX box

setting

In a set of the DX AHU box system, the quantity of slave DX AHU

boxes need to be setted on the master DX AHU box, please refer to

the definition of SW1(table.10-1). If the quantity of slave DX AHU

boxes detected by Master DX AHU box is not equal to the setting

quantity, the master box will display error code 'H7'.

Note：the quantity of slave DX AHU control boxes setting only

need in master DX AHU box.

8-4 DX AHU control box address and

network Address Setting

After first powered on, please set the system address by remote

controller or wired controller, the address of DX AHU box in the same

system can not be repeated.

8-4-1 One DX AHU box controlling one

indoor unit

For one DX AHU box control one indoor unit condition, each DX

AHU box needs to be set an address, this address is an actual

address, when the capacity code ENC1 is selected to be B～F, this

DX AHU box will produce virtual address(es) with corresponding

quantity based on the actual address, please refer to table.8-3. if an

address has been an actual address or virtual address, then this

address can not be the actual address or virtual address of any other

DX AHU box in the same system.

For example, if there are two DX AHU boxes in the same system,

one of the capacity code is D, the setting actual address is 5, then

according to the table.8-3 this control box will produce three virtual

addresses as 6, 7 and 8, and then the actual address and the virtual

address of the other independent control box can not be any one of

5, 6, 7, 8.

The actual address and the virtual address should less than or

equal to 63. When the capacity code is F, it will produce five virtual

address, so the actual address recommended less than or equal 58.
