Setting address method:

The address setting can be realized by setting indoor PCB.

If you use the group control function, there should be a master unit and 15 sets of slave units.

For the master unit, the SW5-3 should be at “ON”. For the slave units, the SW5-3 should be

at “OFF”.

Please refer the below table,
