User Notice

• Never install the wired controller in the moist circumstance or expose it directly under the sunlight.
• Never beat, throw, and frequently disassemble the wired controller and the wireless remote controller.
• Never operate the wired controller and the wireless remote controller with wet hands.
• Do not remove or install the wired controller by yourself. If there is any question, please contact our after-sales service center.
• The wired controller is a general model, applicable for several kinds of units.Some functions of the wired controller are not available for certain kinds of units, more details please refer to the owner’s manual of unit. The setting of such unavailable function will not affect unit’s operation.
• The wired controller is universal. The remote receiver is either in the indoor unit or in the wired controller. Please refer to the specific models.
• As for some indoor units connected with the wired controller, if use the remote controller whose set temperature is adjustable under auto mode, the wired controller will receive the mode signal of remote controller, rather than its set temperature under the auto mode.
• The wired controller is the universal component. When indoor unit has connected with the wired controller, display status of indoor unit is decided by the indoor unit. Valid status and invalid status are all belong to normal status.

Note:
WiFi can be only be reset or turned off by the buttons on the wired controller rather than the remote controller.
WiFi networking performance is related to the distance between the wired controller and the router and the obstacles between them. During the installation process, the distance between the wired controller and the router should be as close as possible, and the obstacles should be as little as possible.
If the WiFi signal is not good, use the WiFi signal enhanced router.
The specific situation depends on the actual installation.

Other Functions

Installation and Dismantlement

Connection of the Signal Line of the Wired Controller

• Open the cover of the electric control box of the indoor unit.
• Let the single line of the wired controller through the soleplate of wired controller.
• Connect the signal line of the wired controller to the 4-pin socket of the indoor unit .
• The communication distance between the main board and the wired controller can be up to 20 meters ( the standard distance is 8 meters)

Installation of the Wired Controller

Table 3

Note:
CN1 is 485 communication interface and it used Wired Controller XE73-44/E for connecting the 4-core communication wire. These two needle stands(CN2aCN3) are used for connecting the smart zone controller. There is no sequence for these two needle stands. You can connect one or two needle stand(s) basing on the requirement. Fig. 21 shows the installation steps of the wired controller, but there are some issues that need your attention.

1. Prior to the installation, please firstly cut off the power supply of the wire buried in the installation hole, that is, no operation is allowed with electricity during the whole installation.
2. Pull out the four-core twisted pair line from the installation holes and then let it go through the rectangular hole behind the soleplate of the wired controller.
3. Stick the soleplate of wired controller on the wall and then use screw M4×25 to fix soleplate and installation hole on wall together.
4. Insert the four-core twisted pair line into the slot of the wired controller and then buckle the front panel and the soleplate of the wired controller together.

For matching with different models, the patch cord and the connection wire are provided in the packaging box of wired controller. As shown in fig. 22.

• If the air conditioner has been installed with the patch cord (fig. 24) used for connecting the wired controller.
Only use the connection wire (fig. 23) in the packing box of wired controller. Connect the terminal (2) to the terminal (4) of patch cord which has been installed on the air conditioner; insert terminal (1) to needle stand CN1 of wired controller. If there’s protection terminal (3), pull out the protection terminal at first and then install it.

Fig. 23: Schematic diagram of connection wire: Connect terminal (1) with wired controller CN1; connect terminal (2) with the terminal (4) of patch cord

Fig. 24: Schematic diagram of patch cord: Terminal (3) is the protection terminal; connect terminal (4) to the terminal (2) of connection wire; connect
terminal (5) to the terminal of wired controller of air conditioner

• If the air conditioner hasn’t been installed with the patch cord used for connecting the wired controller.
  Use the connection wire and patch cord in the packing box of wired controller. Pull out the protection terminal of patch cord at first, connect the connection wire with the patch cord according to fig. 25, and then insert the terminal (1) of connection wire into the needle stand CN1 of wired controller and insert the terminal (5) of patch cord into the terminal of wired controller of air conditioner as well.
  Fig. 25: Schematic diagram after the connection wire and the patch cord have been connected: connect the terminal (2) of connection wire and the
  terminal (4) of patch cord

Fig. 26 shows the schematic diagram of control system connection. XE73-44/E can connect the smart zone controller (integrated control system). “n” indicates the number of communication node address (programmable wired controller XE73-44/E). The complete system is composed of the smart zone controller, wired controller XE73-44/E and communication cable. The wired controller XE73-44/E can support 16 communication node addresses at the most (ns<16).
Terminal A and terminal B of the smart zone controller are respectively connected to the corresponding communication needle stand terminal of the

1wired controller by the communication cable; the other needle stand of #1

wired controller is connected to the #2 wired controller through the telecommunication cable and so forth until connect to the #n wired controller. Except the last wired controller in the control system (only use CN2 or CN3, and the other one will not be connected), there’s no the sequence and the importance for the wired controller. The series number in the figure is only for the sake of clarity.
Fig. 27 shows schematic diagram of DIP switch. There is a 2-bit DIP switch on the main board of wired controller XE73-44/E. As for the last #n wired controller in the control system, the 1-bit and the 2-bit of the DIP switch should be manually pulled to position “on” and position “off” respectively. The DIP switches of other wired controllers should be kept at the initial ex- factory status (1-bit and 2-bit are set at position “off’).

CAUTION!

Please pay special attention to the followings during the connection to avoid the malfunction of the air conditioning unit due to electromagnetic interference.

1. Separate the signal and communication lines of the wired controller from the power cord and connection lines between the indoor and outdoor unit, with a minimum interval of 20cm, otherwise the communication of the unit will probably work abnormally.
2. If the air conditioning unit is installed where is vulnerable to electromagnetic interference, then the signal and communication lines of the wired controller must be the shielding twisted pair lines.
