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.

If you are not connected to Wi-Fi, you will not get 

automatic updates.
