Note:
①If the air conditioner is installed at the strong electromagnetic interference
place, communication line of the wired controller must use shielding twisted
pair.
②Materials of communication line for wired controller must be selected
according to this ins-truction manual strictly.
3.1.2 Installation requirements
(1)Prohibit installing the wired controller at wet places.
(2)Prohibit installing the wired controller at direct sunshine places.
(3)Prohibit installing the wired controller at the place near high temperature
objects or water-splashing places.
3.1.3 Wiring Requirements
There are four network wiring methods between the wired controller and the water
tank/hot water generator:

9
Fig.3.4 Fig.3.5
Fig.3.4 One wired controller controls one water tank or hot water generator.
Fig.3.5 Two wired controllers control one water tank or hot water generator.

Fig. 3.6 One wired controller controls multiple water tanks or hot water generators
simultaneously.

11
Fig. 3.7 Two wired controllers control multiple water tanks or hot water generators
simultaneously.
Wiring instructions:
①When one wired controller controls multiple water tanks or hot water
generators simultaneously, the wired controller can connect to any one water
tank or hot water generator, but the connected ones must be either water
tanks or hot water generators. The total quantity of water tank or hot water
generator controlled by wired controller can't exceed 3 sets, and the
connected water tank or hot water generator must be within the same
network.
Wired Controller XK57

Wired Controller XK57
12
②When two wired controllers control one water tank or hot water generator,
the addresses of those two wired controllers should be different. Please refer
to 3.2.2 Parameter Setting.
③When two wired controllers control multiple water tanks or hot water
generators simultaneously, they can connect to any one water tank or hot
water generator, but the connected ones must be either water tanks or hot
water generators. The addresses of those two wired controllers should be
different. Please refer to 3.2.2 Parameter Setting. The total quantity of water
tank or hot water generator controlled by wired controller can't exceed 3 sets,
and the connected water tank or hot water generator must be within the
same network.
④When one (or two) wired controller(s) control (s) multiple water tanks or hot
water generators at the same time, the controlled water tanks or hot water
generators should have the same setting.
⑤Network connection of wired controller and water tank or hot water
generator must be according to one of the four wiring methods as shown in
fig 3.4-3.7 As for the connection method shown in fig 3.5 and 3.7, 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.

3.1.4 Installation
Fig. 3.8 Installation diagram for wired controller
Fig. 3.8 is the simple installation process of wired controller; please pay attention
to the following items:
(1)Before installation, please cut off the power for water tank or hot water
generator.

(2)Pull out the two-core twisted pair from the installation hole on wall, and then
pull this wire through the connecting hole at the rear side of soleplate of wired
controller.
(3)Stick the soleplate of wired controller on the wall and then use screw M4×25 to
fix the soleplate and installation hole on wall together.
(4)Connect the two-core twisted pair to wiring column H1 and H2 respectively
and then tighten up the screws.
(5)Bundle panel and soleplate of wired controller together and the installation is
completed.
