Caution
First power on, it needs to set the gateway property as the actual conditioner, and then connect the gateway
which has been set to the Air-cooled Scroll system.
* In a Air-cooled Scroll system, there are wire controller and gateway, the address which the address
variable of the gateway (nciCtrl_Addr) corresponds to the address of wire controller must be larger than all
the wire controller addresses (As displayed in Table A).
Gateway address setting example: One Air-cooled Scroll system, there are two wired controllers, the
addresses are 0, 13, and as displayed in Table A, the gateway must be set to 241 or 240, for only 241 and
240 corresponding addresses of wired controller are larger than the wired controller address 13.
The lonworks gateway can be used as a wired controller. If you have chosen our production, please check
the wired controller in the Air-cooled Scroll unit first before using the gateway. If the wired controller in the
Air-cooled Scroll is KJR-08B/BE, the nciType should be set as 1.As the same, if the wired controller in the
Air-cooled Scroll unit is KJR-120A/MBE, the nciType should be set as 0.This is very important.
16.4.7 The network variables which are assigned to the Air-cooled Scroll system:
The network variable of Air-cooled Scroll system: 4 input network variables, used for setting; 8 output
network variables, used for query. As the following figure:
