configured on system run time or calendar days. Reminders

systems, UV lights and HVAC system maintenance. The
type of reminders available are based on the accessories

5.6 Dealer Code
When an 850 Control is connected to the Internet, a Dealer
Code can be entered to auto-populate the dealer’s contact
information and logo. The code is the dealer’s registered
phone number listed on ASDealernet. The Dealer Code is
also used to associate this device with a specific dealer on
the Dealer Diagnostic Portal.
5.7 Software updates
To take full advantage of the features and benefits of the
850, the Control should have the latest software revision
installed.
When the 850 is connected to a Nexia™ Home Intelligence
account, software updates will occur automatically and do
not require user intervention.
The software may also be manually updated. This
procedure requires a computer with an Internet connection,
a USB Flash Drive and the included USB connector. From
a computer, go to www.AmericanStandardAir.com. From
the Products tab, select Thermostat Controls and click on
the 850. Scroll down the page and click on Get Software
Updates and follow the on-screen prompts.
