Press and hold the power button on the Water Heater Controller for about 30 seconds, until you see the connectivity and load LEDs blinking in red/blue/green.
Release the button.
After a few seconds, the connectivity LED will blink in green, which indicates that the previous Wi-Fi profile is wiped out.
Connect your Water Heater Controller again to your home Wi-Fi network.
