precedence.
When several indoor units are set as master, the mode of master indoor unit with a lower
address code will be taken as the master run mode of the unit. when the master indoor unit with the
lowest address code is changed from STOP state to RUN state, the mode of other master indoor
units or slave indoor units shall be kept identical to its mode. otherwise the system will give out
mode conflict error. Therefore, when there are several master indoor units, the address code of the
unit shall be set from lower to higher according to priority level.
5.2 Address Code
The address DIP switch must be set properly for the multi VRF indoor units, otherwise it would
lead to communication trouble. The address code consists of 4 binary bits and is related to the
address ranging from 1-16.
NOTE!
To use multiple indoor units in parallel, make sure to change the setting of address code
before installation and guarantee that the address code of each indoor unit must be different
(The address code is located on the mainboard of indoor unit). If wired controller is used,
make sure to set the address of wired controller to the position same as the address code on
corresponding indoor unit. (The address of wired controller is located on the back of wired
controller)
Below is factory default setting:
The default address code is 0000, that is, the address is 1, shown as the figure above.
Address Code
The address code of the address DIP switch is in binary format. When the switch is set to “ON”,
it indicates “1” of the binary system, and “0” when set to the oppoiste side.

Example 1: If the address code is “1110”, that is, switch 4 is set to “ON”, and switch 3,2 and 1
are all set to the opposite side, in this case, the address is “8”.
Example: If the address code is “0101”, that is, the switch 3 and 1 are set to “ON” while switch
4 and 2 are set to the opposite side, in this case, the address is “11”.
