You only need to reset the AC Controller if you have a HomeKit configuration problem.
You do not need to reset the AC Controller in the event of:
- Loss of Wi-Fi connection.
- Wi-Fi reconfiguration.
- Unexpected heating behaviour.
- Plug the AC Controller into a 230V socket using the mains adapter. The LED should blink five times then go out.
- Press and hold the AC Controller RESET button located at the back of the product for 20 seconds. For the first 15 seconds, the LED will blink slowly (glow). Keep pushing the button until the LED stops blinking then blinks quickly five times. HomeKit and Wi-Fi credentials are deleted in this operation.
