master indoor unit automatically. Then you can reset the master indoor unit by remote controller or
wired controller.
4.2.1 Setting by remote controller
Point the remote controller at the light board or wired controller
In fan mode, set master mode indoor unit through ▲ and ▼ button:
(1) Adjust set temperature to 30℃.
