The error E02 on the Smart AC Control indicates that the Wi-Fi connection has been lost. If you see this error, do the following:
Check that Wi-Fi is enabled and working, by checking Wi-Fi access on other devices or by checking the router.
Check whether the Wi-Fi password has been changed. If this is the case you can delete the current network data and connect your Smart AC Control to a new network.
If none of the above is the case, check the distance of the Smart AC Control to your router. Does the error disappear when moving closer to the router? In this case the Wi-Fi signal is not strong enough in the Smart AC Control’s location and a new location closer to the router has to be selected.
If you have further questions about your Smart AC Control Wi-Fi connection, please contact us.
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.
