Use this feature in climates where both air conditioning and heating are used on the
same day. When the system mode is in Auto, the thermostat automatically selects
heating or cooling depending on the indoor temperature.
While in the Auto mode, if a schedule override takes place (temporarily or perma-
nently) the thermostat will automatically adjust the cooling and heating settings to
maintain a 3-degree separation between the cool and heat settings.
For example, if the heat temperature is raised to where it gets within 3-dgrees of the
cool setting, the display will show an up arrow next to “cool” to show the thermostat
is raising the cool setting up to maintain a 3-dgreee separation.
The display will also show both “Auto” and either “Heat” or “Cool” for which tempera-
ture setting you are currently adjusting. Press the system button to select between
the heat and cool to view/adjust either mode.

Auto Changeover
If the cool temperature is lowered to where it gets close to the heat setting, an arrow
next to heat will show the thermostat is lowering the heat setting down to maintain a
3-degree separation.
CAUTION: To avoid possible compressor damage, do not use Auto Changeover if the
outside temperature drops below 50°F (10°C).
The triangle indicates the cool temperature is
increasing to maintain 3 degrees between heat
and cool settings.

About your new thermostatSpecial 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).

Battery replacement/Customer assistance
Batteries are optional (to provide backup power) if
your thermostat was wired to run on AC power when

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.
