Error E05 occurs when the hostname could not resolve to the IP address using DNS. Go to the DNS settings in your router and change the DNS server to a different one used. We recommend using Google DNS for those countries where it is available. To set your DNS settings to use Google DNS, set the address of the DNS server to “8.8.8.8” and the address of the alternative DNS server to “8.8.4.4”.

Tip: You can always control your AC directly on the Smart AC Control even when the internet connection is temporarily unavailable.You can also use your old AC remote for this.
