Once the thermostat is connected to the internet through WiFi and after a 5 minute period,
it will automatically download the most up to date communicating software available. See
the image below of a thermostat software update.
This software update should take approximately 1 minute. Once the software update is
completely installed, restore factory defaults. To restore the thermostat factory defaults
enter the installer service menu by pressing the gear icon on the home screen then press
and hold the service van icon as shown below.
