If this is a situation where you have changed your Wi-Fi password or system ID and password, then all you have to do is wake up the thermostat, rotate the ring to menu, select, then rotate to ring to net work, then you will be asked to either type the name of the Netwerk SSID or, rotate the ring to the new network SS ID, select it, then type in the password.
there’s no sense resetting the entire unit to factory settings just to change the network when it has a built-in ability to change your Wi-Fi network or password. If the Wi-Fi networks still exist in the password change, the thermostat will tell you that you need to enter the new password because it will know that it no longer works.
