is required. The reminder is time-based and can be
configured on system run time or calendar days. Reminders
can be configured for humidifiers, filters, ventilation
systems, UV lights and HVAC system maintenance. The
type of reminders available are based on the accessories
enabled in the installer settings.
5.6 Dealer Code
When an 824 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 ComfortSite. 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
824, the Control should have the latest software revision
installed.
When the 824 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
the computer, go to www.Trane.com/residential and select
Thermostat & Controls. Click on the 824, select Download
Latest Version Software and follow the on-screen prompts.
