2. Check of Wi-Fi interface (MSZ-AP∙VGK)
Follow the procedure below if the air conditioner cannot be monitored or controlled with a device such as a smartphone.
Connect the Wi-Fi interface and the router by referring to
SETUP QUICK REFERENCE GUIDE and SETUP MANUAL. If
the connection failed, check the following and connect the Wi-Fi
interface and the router again:
- Make sure that communication distance is not too far between
the Wi-Fi interface and the router. Move the router closer to the
Wi-Fi interface.
- Make sure that the router uses WPA2-AES encryption.
- Make sure that the number of the connected devices to the
router does not exceed the limit.
Check the instruction manuals for the router and the device such as a
smartphone, and enable the Internet access.
There is a problem in communication between the air conditioner and
the Wi-Fi interface. Check whether the air conditioner can be oper-
ated with a remote controller.
If the air conditioner does not operate, Check indoor/outdoor connect-
ing wire and the power supply. (Check the indoor electronic control
P.C. board.)
If the indoor/outdoor wire is connected and the power supplied, hold
down the RESET switch of Wi-Fi interface for 2 seconds. The com-
munication with the air conditioner is normal if the UNIT lamp starts
blinking. (It may take a few minutes to blinking.)
If the problem persists, check the cable and the connector of Wi-Fi
interface.
If all else failed, replace the Wi-Fi interface.
If not improve it even if replace the Wi-Fi interface, replace the indoor
electronic control P.C. board.
