4.2.2 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.

NOTES!

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)

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”.
