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.
◆In one system network, you must set one indoor unit as the master indoor unit,
Other indoor units are slave indoor units .
◆The operation mode of the system is basing on that of master indoor unit.
Master indoor unit can switch to any modes, while slave unit can’t switch to the
mode that is conflicting with master indoor unit.
◆When master indoor unit changes mode which cause operation mode of
slave indoor unit conflicts with that of system, the operation mode of slave unit
will switch to the operate mode of system automatically.
◆When two wired controllers control one (or more) indoor unit(s), the address of
wired controller should be different.
◆Functions with “*”are optional for indoor units. If a function is not included in an

Fig. 5.5 One wired controller controls multiple indoor units simultaneously
Wired Controller XK46
Fig. 5.6Two wired controllers control multiple indoor units simultaneously
Wiring instructions:
(1) When one wired controller controls multiple indoor units simultaneously, the
wired controller can connect to any one indoor unit, but the connected indoor
unit must be the same series indoor unit. 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 indoor unit's network. Wire controller must set
quantity of group control indoor units. Please refer to 5.2.3 Parameters Setting.
(2) When two wired controllers control one indoor unit, the addresses of those two
wired controllers should be different. Please refer to 5.2.3 parameter setting.

(3) When two wired controllers control multiple indoor units, wired controller can
connected to any one indoor unit, while the connected indoor unit should be
the same series indoor unit. The addresses of those two wired controllers
should be different. Please refer to 5.2.3 parameter setting. The total quantity
of indoor unit controlled by wired controller can't be more than 16 sets and all
connected indoor units must be within the same indoor unit network. Wire
controller must set quantity of group control indoor units. Please refer to 5.2.3
Parameters Setting.
(4) When one (or two) wired controller(s) control(s) multiple indoor units at the
same time, the controlled indoor unit's setting should be the same.
(5) Wiring of wired controller and indoor unit network must be according to one of
the four wiring method as shown in fig 5.3-5.6. As for the connection method
shown in fig 5.4 and 5.6, there should be only one master wired controller
(address is 01) and one slave wired controller (address 02). The quantity of
wired controller can't exceed two.
Note:
Series of indoor units include:①Common Multi VRF Units;②Fresh Air Units;③
Double-heat Sources Units;④Combined Units; Except for fresh air units,
double-heat sources units and combined units, the rest of indoor units belong to
common multi VRF units.
