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 aect 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 specic models.

4.15 WIFI FUNCTION SETTING
It is possible to connect remotely to the system using this function and the EWPE Smart App for iOS and Android devices (available free on Apple Store and Google Play).
EWPE Smart App can only set some common functions of WiFi wired controller: ON/OFF, mode, set temperature, FAN speed, etc.
When using the EWPE Smart App for the rst time, please reset the WiFi function of wired controller (reset WiFi to ex-factory setting): Under o status, press “FUNCTION” +
“FAN” combination buttons on its wired controller for 5s. Once “oC” is displayed,this indicates that reset was successful.
If there is a communication failure for WiFi, after resetting WiFi, the temperature display area of wired controller displays “JF” for 5 seconds, which indicates that the current
reset is invalid.
Press FUNCTION under on state of the unit till the unit enters the WiFi setting interface, the temperature area will display the WiFi status.
Press “ ” or “ ” button to turn on WiFi(“ON”is displayed) or turn o WiFi (“OFF” is displayed), and then press “SWING/ENTER”button to conrm it.
Note:
WiFi can be only be reset or turned o 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 specic situation depends on the actual installation.
4.16 OTHER FUNCTIONS
1. LOCK
Upon startup of the unit without malfunction or under the“OFF”state of the unit, press“ ”and “ ”at the same time for 5s till the wired controller enters the Lock function.
In this case, LCD displays . After that, repress these two buttons at the same time for 5s to quit this function.
Under the Lock state, any other button press won’t get any response.
2. MEMORY
Memory switchover: Under the “OFF”state of the unit, press Mode and“ ”at the same time for 5s to switch memory states between memory on and memory o. When this
function is activated, Memory will be displayed. If this function is not set, the unit will be under the “OFF”state after power failure and then power recovery.
Memory recovery: If this function has been set for the wired controller, the wired controller after power failure will resume its original running state upon power recovery.
Memory contents: ON/OFF, Mode, set temperature, set fan speed and Lock function.
3. SELECTION OF THE TEMPERATURE SENSOR
Under OFF state of the unit, press both“FUNCTION”and“TIMER” for ve seconds to go the commissioning status. Under this status, adjust the display in the temperature dis-
play area to“00” through the button “MODE”, and then adjust the option of the temperature sensor in the timer display area through the button “ ” or " ".
1. Indoor ambient temperature is sensed at the return air inlet (01 in the timer display area).
2. Indoor ambient temperature is the sensed at the wired controller (02 in the timer display area).
3. Select the temperature sensor at the return air inlet under the cooling, dry and fan modes, while select the temperature sensor at the wired controller under the heating
and auto modes. (03 in the timer display area).
4. Select the temperature sensor at the wired controller under the cooling, dry and fan modes, and select the temperature sensor at the return air inlet under the heating
mode and auto modes (04 displayed in the timer display area).
After the setting, press "SWING/ENTER" to make a conrmation and quit this setting status.
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: 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, oor 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.
4. SELECTION OF THE FAN SPEED
Under OFF state of the unit, press both the buttons "FUNCTION" and "TIMER" for ve seconds to go to the commissioning status, and then adjust the display in the temperature
display area to 01 through the button “MODE”and adjust the setting of the fan speed, which comes to two options:
— 01: Three low fan speeds;
— 02: Three high fan speeds.
After the setting, press "SWING/ENTER" to make a conrmation and quit this setting status.
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: In the back side of the Wired Controller, it is possible to nd:
— CN1, which is RS485 communication interface and is used for connecting the panel to the unit using a 4-core communication wire;
— CN2 and CN3, which are used for connecting the CC2 Accessory if desired.
There is no sequence for these two needle stands. You can connect one or two needle stand(s) basing on the requirement.
Fig. 18 shows the installation steps of the wired controller, please pay attention to the following notes:
1. Prior to the installation, please rstly cut o 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 x soleplate and installation hole on wall together
4. Insert the four-core twisted pair line into the slot of the wired controller.
5. Buckle the front panel and the soleplate of the wired controller together.
For matching with dierent models, the patch cord and the connection wire are provided in the packaging box of wired controller. As shown in g. 19.

— The sequence in which the indoor units are connected does not matter, except for the last panel (only use CN2 or CN3 and connect nothing else).
