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.
While the update is taking place, your thermostat screen
flashes
Updating
and shows the percentage of the update
that has occurred. When the update is complete, your
home screen will appear as usual.
Note: If you are not connected to Wi-Fi, you will not get
automatic updates.
