Delta T Alerts And Utility Saver Switches; Data Logs - Honeywell Home THX9321 Prestige 2.0 Manual

Delta T Alerts and Utility Saver
Switches
For systems that might be interrupted by a utility saver
switch (conventional cooling and heat pumps in the heat
and cool mode), the thermostat will ask if a utility saver
switch is installed and provide an option to the user to turn
off diagnostics temporarily while power is interrupted by
the utility company. Diagnostics can be turned off for 1-14
days.

Data Logs

The Data Logs collect system information that can help
point a service technician in the right direction when
troubleshooting.
When accessing the Data Logs, the installer can turn off
each log, delete current log entries, and save Data Logs to a
memory stick via the USB port. See "Using the Data Logs"
beginning on page 91 and "To save a Data Log to a
memory stick" beginning on page 92 for more information.
Data Logs include the Alerts Log, User Interactions Log,
and Performance Logs.
Alerts Log
The Alerts Log stores a history of the most recent 25 alerts
and records the date and time of each alert. In the Alerts
Log, press any of the alerts for more information.

You can also press Show Active Alerts to display the active
alerts that are currently snoozed by the user. This allows
the service technician to dismiss alerts for problems that
have been corrected, and prevent unnecessary callbacks.
The Alerts Log contains information about the alert and
system information. See Fig. 166–171 as an example.
