• Tighten the xing screws to the PCB terminal with less than 6N·cm torque. When the screws are tightened with
more than 6N·cm torque, the screw thread will be damaged.
6. Run the Wi-Fi kit.
f When the Wi-Fi kit is turned on, all the lamps are turned on until system operates.
f After the system operates, tracking is performed automatically.
7. Perform the tracking.
❋ Tracking :You can search the devices connected to the Wi-Fi kit with the tracking function. The devices connected to Wi-Fi
kit recognize that they are connected to the Wi-Fi kit. To monitor or control the system air conditioner with Wi-Fi
kit, tracking should be performed.
f When the Wi-Fi kit is turned on, the tracking is performed automatically. During the tracking, the lamp of
the Wi-Fi kit ( ) ( ) blinks.
f If the tracking is completed but the lamp ( ) blinks, it means the Wi-Fi kit does not nd connected indoor units. In this
case, check whether the connection of communication cable between indoor unit and outdoor unit is correct or is
aected by noise.
f If the conguration of indoor unit or outdoor unit is changed, tracking should be performed again manually by pressing
the button (SW3) inside the Wi-Fi kit. (Ⓑ-)
• If you want to control the indoor unit with the Wi-Fi kit, indoor unit’s centralized control usage option must be set to
“Enable”.
• If you want to control the indoor unit with the Wi-Fi kit, tracking must be done properly and connect the Wi-Fi kit to
a wired/wireless router.
• When the tracking is completed correctly, the lamp ( ) is turned on until the process which connects the wired/
wireless router to Wi-Fi kit is completed.
