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 (RTH7500 only): 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
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.
