Software updates
Resideo periodically issues updates to
the software for this thermostat. The
updates occur automatically through
your WiFi 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 Resideo
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 WiFi
or registered at Total Connect Comfort,
you will not get automatic updates.
If you have difficulty with your thermostat, please try the following suggestions.
Most problems can be corrected quickly and easily.
