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 first time, please reset the WiFi function of wired controller (reset WiFi to ex-factory setting): Under off 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 off WiFi (“OFF” is displayed), and then press “SWING/ENTER” button to confirm it.
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.

3. SELECTION OF THE TEMPERATURE SENSOR
Under OFF state of the unit, press both “FUNCTION” and “TIMER” for five 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

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, 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.
