    What to do when trying to make a direct connection to the adapter (AP mode) and the Wireless LAN adapter is not visible in the available Wi-Fi networks list of the phone/tablet with my Daikin Siesta ATXM20N2V1B Air Conditioner?

      If the AP LED is not lit, press the MODE button for 2 seconds to switch to AP mode. If the AP LED is blinking, please wait until the AP LED is lit (approximately 1 minute). The Wireless LAN adapter is still starting up. If the AP LED is lit, switch to RUN mode by pressing the MODE button for 2 seconds. Now switch back to AP mode by pressing the MODE button again for 2 seconds. This procedure will change the wireless channel on which the Wireless LAN adapter is operating. Repeat if necessary.

      Check that the power is on and the RUN LED is lit. If the AP LED is lit, press the MODE button for 2 seconds to switch to RUN mode. If the RUN LED is blinking, try connecting the WLAN adapter to the wireless network again. Make sure the Wireless LAN adapter is close enough to the router (Wireless LAN access point). If the RUN LED is lit, make sure that the smartphone or tablet is connected to the same wireless LAN network as the Wireless LAN adapter.

    Why does my Daikin Siesta ATXM20N2V1B Air Conditioner system suddenly stop operating?
    • A
      Andrea SimpsonAug 21, 2025
      Check to ensure that the air inlet or outlet of both the outdoor and indoor units are not blocked by any obstacles. Remove any obstructions to allow free airflow. Also, the air conditioner might stop temporarily due to large voltage fluctuations to protect itself, but it should resume operation automatically after about 3 minutes.
