Software updates
Honeywell periodically issues updates to the software for
this thermostat. The updates occur automatically through
your Wi-Fi connection. All your settings are saved, so
you will not need to make any changes after the update
occurs.
While the update is taking place, your thermostat screen
goes blank and the message center shows UPDATING
and the percentage of the update that has occurred.
When the update is complete, your home screen will
appear as usual.
Note:
If you are not connected to Wi-Fi or registered at
Total Connect Comfort, you will not get automatic updates.
Smart Response Technology
This feature allows the thermostat to "learn"
how long the heating/cooling system takes to
reach programmed temperature settings, so the
temperature is reached at the time you set.
For example: Set the Wake time to 6:00 am, and
the temperature to 70°. The heat will come on
before 6:00 am, so the temperature is 70° by
6:00 am.
Note: System setting function 0530 controls
Smart Response Technology. See "Smart
Response Technology" on page 23.
Compressor protection
This feature forces the compressor to wait
a few minutes before restarting, to prevent
equipment damage.
The message "Recovery" is
displayed when the system is
activated before a scheduled time
period.
During the wait time, the message
"Wait" is displayed on screen.
