User Notice

◆ Never install the wired remote controller in highly humid environments or expose to direct

sunlight.

◆

Never drop, shake, toss or frequently disassemble the wired remote controller or the wireless

remote controller.

◆

Never operate the wired remote controller and the wireless remote controller with wet hands.

Do not remove or install the wired controller by yourself. If you have questions, please contact

◆

your local licensed HVAC technician.

This wired controller is compatible with several kinds of units.

◆

Some functions of the wired controller are not available for certain units,IRU more details please

refer to the owner’s manual of unit. Selecting an unavailable function will do nothing and 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.

When some indoor units are connected to the wired controller and the remote controller is set in

◆

the auto mode (where the temperature adjusts automatically), the remote controller will override the wired controllers auto mode setting.

Please read the manual carefully before installing and using this product.

Pressing the button “On/Off” also can quit this commissioning status but the set data won’t be

memorized.

Under the commissioning status, if there is no any operation in 20 seconds after the last button

press, it will back to the previous state without memorizing the current data.

Note:

After connected with indoor unit, if the type of ambient temperature sensor has not been manually

set, the wired controller will select the ambient temperature sensor according to the model of connected

IDU; if it connects to cassette type IDU, duct type IDU, floor ceiling type IDU, ceiling type IDU, it will adopt ③, otherwise it will adopt ①. If the type of ambient temperature sensor is set manually, the wired

controller will subject to the manual setting, and will not set according to automatic IDU model selection.

Pressing the button “On/Off” also can quit this commissioning status but the set data won’t be memorized.

Under the commissioning status, if there is no any operation in 20 seconds after the last button

press, it will back to the previous state without memorizing the current data.

4 Installation and Dismantlement

4.1 Connection of the Signal Line of the Wired Remote Controller

● Open the cover of the electric control box of the indoor unit.

● Let the single line of the wired remote controller through the rubber ring.

● Connect the signal line of the wired remote controller to the 4-pin socket of the indoor unit .

● Tighten the signal wire with ties.

● The communication distance between the main board and the wired remote controller can

be up to 20 meters ( the standard distance is 8 meters)

Note：CN1 is 485 communication inter face and it used

for connecting the 4-core commu nication wire. These two needle stands(CN2 、CN3) are used for connecting the smart zone controll er. There is no sequence for these two needle stands. You can connect one or two needle stand(s ) basing on the requirement.

Fig.15

Fig.15 shows the installation steps of the wired remote 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 remote 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, attach the sponge 20×20×2 at the screw hole

and then press it with fingers to make sure it’s attached firmly.

(4). Insert the four-core twisted pair line into the slot of the wired remote controller and then

buckle the front panel and the soleplate of the wired remote controller together.

one controller (integrated control system). “n” indicates the number of communication node address

z (programmable wired controller XE71). The complete system is composed of the smart zone controller, wired controller XE71 and communication cable. The wired controller XE71can support 16 communication

node addresses at the most (n≤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.

ontroller XE71(XE71-44/G). As for the last #n wired controller in the control system, the 1-bit and the 2-bit of the

c 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 following during the installation to avoid any problems with

the air conditioning unit due to electromagnetic interference.

① .

Separate the signal and communication lines of the wired remote controller from the power

Page 19

Wired Remote Controller XE71-44/G

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 remote controller must be the shielding

twisted pair lines.
