2 Operation Notices
The power supply for all indoor units must be unified.
Prohibit installing the wired controller at wet or sunshine places.
Do not knock, throw or frequently disassemble the wired controller.
Do not operate the wired controller with wet hands.
When the system mode priority is the master-slave mode, in one system network,
you must set one indoor unit as the master indoor unit, Other indoor units are slave
indoor units .
When the system mode priority is the master-slave mode, the operation mode of
the system is basing on that of the master indoor unit. The master indoor unit can
be set to any mode (including auto mode), while the slave indoor unit can’t set to
the mode that conflicts with the system mode.
When the system mode priority is: Cooling mode is prioritized, heating mode is
prioritized, first-set mode is prioritized, or last-set mode is prioritized. The indoor
unit can be set to any mode (excluding auto mode). The indoor unit will
automatically switch to the system mode, when the operation mode of the indoor

Wiring instruction:
(1) When one wired controller controls multiple indoor units simultaneously, the
wired controller can connect to any one indoor unit, but the connected ones
must be units of the same series. The total quantity of indoor unit controlled
by wired controller can't exceed 16 sets, and the connected indoor unit
must be within the same network. The number of indoor units in group
control must be set. Please refer to section 5.2.2 Parameter Setting for the
setting method.
(2) When two wired controllers control one indoor unit, the addresses of those
two wired controllers should be different. One should be master controller
and the other should be slave controller. Please refer to section 5.2.2
Parameter Setting for the setting method.
(3) When two wired controllers control multiple indoor units simultaneously,
they can connect to any one indoor unit, but the connected ones must be
units of the same series. One should be master controller and the other
should be slave controller. Please refer to 5.2.2 Parameter Setting for the
setting method of master and slave wired controllers. The total quantity of
units controlled by wired controller can't exceed 16 sets, and the connected
indoor units must be within the same network. The number of units in group
control must be set. Please refer to section 5.2.2 Parameter Setting for the
setting method.
(4) When one (or two) wired controller(s) control (s) multiple indoor units at the
