Data Logs

The Data Logs collect system information that can help
point a service technician in the right direction when
troubleshooting.
To access a Data Log, it must be saved to a MicroSD card.
See "Using the Data Logs" beginning on page 74 and
"MicroSD card" beginning on page 101 for more
information.
Data Logs include the Alerts Log and the User Interactions
Log.
Alerts Log
The Alerts Log stores a history of the most recent 25 alerts
and records the date and time of each alert. It can be
turned on, off, and reset at the thermostat.
The Alerts Log contains information about the alert and
system information.
The Alerts Log can include:
• The alert name and description.
• System details at the time of the alert.
• The alert status (snoozed, dismissed, recovered).
User Interactions Log
The User Interactions Log can help a service technician
save time by determining if the issue is related to a system
problem or an accidental user error.
The User Interactions Log records the date and time for
most changes made by the user, whether made at the
thermostat or from a remote location (smart phone, tablet,
web, or Portable Comfort Control, etc.). The log saves the
most recent 250 user changes, including:
• Indoor Air Quality Settings
• Maintenance Reminders
• Temperature Settings
• System/Fan Mode
• Alerts (snoozed or dismissed)
• Installer Setup
• Date/Time
The User Interactions Log can be turned on, off, and reset
at the thermostat.
