User's Manual for Wired
Controller XK55
User’s Notice
The power supply method 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.
Dot not operate the wired controller with wet hands.
The photos in this instruction manual is only for reference, Please refer to the
actual products for the final effect.
In one system network, you must set one indoor unit as the master indoor unit.
Others are slave indoor unit.
The operation mode for the system is basing on that of master indoor unit.
Master indoor unit can switch the mode freely, while slave indoor unit can’t
switch to the mode which will conflict with the master indoor unit.
When the operation mode of indoor unit is conflicting with that of system
because the master indoor unit is changing mode, the operation mode of
slave indoor unit will switch to the operation 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 indoor unit, wired controller can’t set the function, or setting of this function
is invalid to the indoor unit

Caution:
① If the air conditioner is installed the place with strong magnetic interference,
the communication wire of wired controller must use shielding twisted pair
wire.
② The communication wire of the wired controller must be selected according to
this manual. Prohibit selecting the communication wire which is not comply
with the requirement of this manual.
③ When operating two wire controllers, master wired controller and slave wired
controller can’t be this wire controller.
1.2 Installation requirement
(1). Prohibit installing the wired controller at wet place.
(2). Prohibit installing the wired controller at sunshine place.
(3). Prohibit installing the wired controller at the place where is closing to
high-temperature objects or with splashing water.
(4). Prohibit installing the wired controller at the place where is facing to the
window to prevent the interference from the same model remote controller in
neighbor.

Wiring instruction:
(1). When one wired controller controls more indoor units at the same time, wired
controller can be connected to any one indoor unit and the connected indoor unit
should be in the same series. The maximum quantity of indoor units controlled by the
wired controller can’t exceed 16 sets and the connected indoor units should be in the
same system. Wired controller should set the Number of IDUs. Please refer to 3.2.12
Engineering Setting Page for the detailed setting method.
(2). When two wired controllers control one indoor unit, the addresses for those
two wired controllers should be different. Please refer to the page of Engineering
Setting for the address of wired controller.
(3). When two wired controllers control more indoor units, the wired controller can
be connected to any one indoor unit. The connected indoor unit should be in the
same series. The addresses for those two wire controllers should be different (set at
3.2.12 Engineering Setting page). The maximum quantity of indoor units controlled
by the wired controller can’t exceed 16 sets and the connected indoor units should be
in the same system. Wired controller should set the Number of IDUs. Please refer to
3.2.12 Engineering Setting Page for the detailed setting method.
(4). When one (or two) wired controller (s) control (s) more indoor units, the
setting for the controlled indoor unit should be the same.
(5). The wiring between wired controller and indoor unit must be according the
wiring method of fig 1.4-1.7. In the wiring method of fig 1.5 and fig 1.7, only one
master wired controller (address 1) and one slave wired controller (address 2) can be

set. 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; ④ Combined Units; Except for fresh air units,
double-heat sources units and combined units, the rest of indoor units belong to

Please pay attention to below items:
(1). Please disconnect the power support for indoor unit before installation. The
power must be disconnected during the whole installation process.
(2). Pull out the 2-core dual twisted pair wire from the installation hole on wall and
then pull it through the wiring hole at the back of soleplate plate of wired controller.
(3). Stick the soleplate on the wall and then use screw M4X25 to fix sole plate
and installation hole on the wall together.
(4). Connect the two-core twisted pair wire to H1 and H2 wiring terminal and then
tighten screws.
(5). Finally, bind the panel of wired controller and sole plate of wired controller
together.
