Battery replacement
M28391
Batteries are optional (to provide
backup power) if your thermostat
was wired to run on AC power when
installed.
Install fresh batteries immediately when
the LO BATT warning begins flashing.
The warning flashes about 30 days
before batteries are depleted.
Even if the warning does not appear,
you should replace batteries once a
year, or before leaving home for more
than a month.

Special features
Smart Response®Technology: This feature allows the thermostat to
“learn” how long the furnace and air conditioner take to reach programmed
temperature settings, so the temperature is reached at the time you set. For
example: Set the Wake time to 6 am, and the temperature to 70°. The heat will
come on before 6 am, so the temperature is 70° by the time you wake at 6.
The message “Recovery” is displayed when the system is activated before a
scheduled time period.
Compressor Protection: This feature forces the compressor to wait a few
minutes before restarting, to prevent equipment damage. During the wait time,
the message “Wait” is displayed on screen.
Auto Changeover: This feature is used in climates where both air conditioning
and heating are used on the same day. When the system is set to Auto,
the thermostat automatically selects heating or cooling depending on the
indoor temperature. Heat and cool settings must be at least 3 degrees apart.
The thermostat will automatically adjust settings to maintain this 3-degree
separation.
CAUTION: To avoid possible compressor damage, do not use Auto
Changeover if the outside temperature drops below 50°F (10°C).
