Group Control
The group control can control 16 rooms(64 indoor units/standard) with
a wired controller. When a whole unit is operating, each unit operates
in the same mode(such as mode settings and the fan speed, etc.).
To control each unit separately, you can control it with the centralized
controller or PC controller(S-Net) too. However, the group control and
the separate control can' t be operated at the same time.
