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 (RedLINK Internet Gateway, 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
Performance Logs

The thermostat contains the following logs:
• Cooling Performance Log
• Heating Performance Log
• Emergency Heat Performance Log
• Run Time by Equipment Type
• Indoor and Outdoor Conditions Log

The Performance Log records the following information:
• Minimum and Maximum Delta T
• Minimum and Maximum Discharge Temperature
• Minimum and Maximum Return Temperature
• Minimum and Maximum Outdoor Temperature and Humidity
• Minimum and Maximum Indoor Temperature and Humidity
• Run Time of Heating and Cooling per stage

You have the option to view this data in 4 different time periods:
• Hourly - saves data for the last 8 days.
• Daily - saves data for the last 15 days.
• Weekly - saves data for the last 8 weeks.
• Monthly - saves data for the last 25 months.
NOTES:
— Data is collected in the Emergency Heat Perfor-
mance Log only if the thermostat was set to the
“Emergency Heat” mode.
— The Run Time by Equipment Type Log contains
the Total Run Time of each equipment type since
the last time it was reset.
— The Minimum and Maximum Delta T, Discharge
Temperature and Return Temperature are only
shown in the log if the equipment ran for at least 5
minutes during a cycle. If the equipment ran for
less than 5 minutes in every cycle during a 1 hour
period, the log will display “--°.”
— For Air to Air Heat Pumps, the Minimum Delta T
and Minimum Discharge Temperatures will include
defrost cycles in the log.
