Software Updates; Troubleshooting - Honeywell 9000 Guide De L'utilisateur

Software updates

Honeywell periodically issues updates
to the software for this thermostat. The
updates occur automatically through
your Wi-Fi connection. All your settings
are saved, so you will not need to make
any changes after the update occurs.
Updates occur in the early morning. After
your thermostat receives the software, it
reboots, briefly displaying the Honeywell
logo. The screen then shows "Updating
software..." with a green progress bar.
When the update is complete, your home
screen will appear as usual.
Note: If you are not connected to Wi-Fi
or registered at Total Connect Comfort,
you will not get automatic updates.
