Program Schedule
You can program four time periods each day, with different settings for
weekdays and weekends. We recommend the pre-set settings (shown in the
table below), since they can reduce your heating/cooling expenses.
Wake - Set to the time you
awaken and the temperature
you want during the morning,
until you leave for the day.
Leave - Set to the time
you leave home and the
temperature you want while you
are away (usually an energy-
saving level).
Return - Set to the time
you return home and the
temperature you want during
the evening, until bedtime.
Sleep - Set to the time you go to bed and the temperature you want overnight
(usually an energy-saving level).
NOTE: Leave and Return periods can be canceled on weekends.

CAUTION: To avoid possible compressor damage, do not use Auto
Changeover if the outside temperature drops below 50°F (10°C).
Auto changeover
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 permanently) 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-degrees 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-degree separation.
The display will also show both “Auto” and either “Heat” or “Cool” for which
temperature setting you are currently adjusting. Press the system button to
select between the heat and cool to view/adjust either mode.

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.

Turn thermostat over, insert

Battery replacement
M28420
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.
